Green Bay — A year after figuring out that young quarterbacks Graham Harrell and B.J. Coleman were not good enough to play in the NFL, the Green Bay Packers are back in the market for a young prospect or two.

Coach Mike McCarthy has said this off-season that he would like to have a fourth quarterback in camp alongside Aaron Rodgers, Matt Flynn and Scott Tolzien, and it appears he wasn't just making conversation.

The Packers are going to add another quarterback either through the draft or in the rookie free agency that immediately follows. There's no other conclusion one can make after the Packers hosted four quarterbacks on predraft visits this spring.

Here are the four:

■ Tom Savage, Pittsburgh, 6 feet 4 inches, 228 pounds.

■ David Fales, San Jose State, 6-2, 212.

■ Keith Wenning, Ball State, 6-25/8, 218.

■ Brock Jensen, North Dakota St., 6-2½, 223.

While predraft visits don't necessarily signal a team's interest in a player — some teams use them as diversion tactics and others use them to double-check medical issues — the Packers tend to bring in players they are interested in drafting in the late rounds or signing as free agents.

They almost never bring in a prospect they're going to draft on the first two days.

In this case, the four quarterbacks can be characterized as late-round/free-agent types, although Savage reportedly has been moving up draft boards and could be taken in the second or third round. The Packers are looking for someone to either challenge Tolzien for the No. 3 spot or push out Flynn if Tolzien proves he is the best choice for backup.

Savage is a bit of a mystery because he transferred twice — from Rutgers to Arizona and then Arizona to Pittsburgh — and sat out a full two years before former Wisconsin offensive coordinator and current Panthers coach Paul Chryst took him under his wing.

After playing 18 games in which he attempted just 192 passes at Rutgers, Savage left for Arizona. But after the Wildcats changed coaches, he transferred again and so from the end of the 2010 season to the start of 2013, he didn't play a down.

Last season he completed 238 of 389 passes (61.2%) for 2,958 yards and 21 touchdowns with nine interceptions, but he often looked indecisive and took 43 sacks.

But the more scouts saw Savage's big arm and nice delivery they became more interested.

"He certainly has a lot of the talents and physical attributes," Chryst said recently. "The biggest thing Tom hasn't done is just play a lot of football."

With McCarthy's connection to Pitt — he grew up in Pittsburgh and was a graduate assistant for the Panthers — Savage could be on his radar. The big question is whether the Packers are willing to give up a second-day pick for him.

More than likely, they'll consider Wenning or Fales, a couple of prolific passers with less natural ability and weaker arms than Savage.

Wenning set almost every single-season and career passing record in Ball State history, finishing with 4,148 yards, 35 touchdowns and seven interceptions in 12 games last year. He has drawn a lot of interest and taken a number of visits.

Wenning ran the 40-yard dash in 4.99 seconds, had a 28-inch vertical and has good-sized hands (10 inches).

Fales drew a lot of attention when San Francisco 49ers coach Jim Harbaugh called him one of the top five quarterbacks in the draft. But there are questions about Fales' arm strength and whether he can make the deep sideline throws. He started out at Nevada but wasn't equipped to be the next Colin Kaepernick and settled into the starter's job at San Jose State.

His hands measure only 9¼ inches and he ran the 40 in 4.99. He's confident, has a good release and is willing to make the tough throw, but he may have trouble succeeding outside the pocket.

In two seasons, he completed 639 of 938 passes (68.1%) for 8,382 yards and 66 touchdowns with 22 interceptions (161.7 rating).

The other quarterback — Jensen — played at Waupaca before heading off to North Dakota State. He led the school to three straight FCS championships and finished with a 47-5 record.

In four seasons, he completed 703 of 1,124 passes (62.5%) for 8,598 yards and 72 touchdowns with 21 interceptions. At his pro day, he ran the 40 in 4.7 and registered an impressive 34-inch vertical jump.

His small-school background will affect his draft status, but the Packers may be intrigued enough to make him part of their highly valued rookie free-agent class. As those who follow the Packers know, general manager Ted Thompson and McCarthy don't discriminate against those who aren't drafted.

Here is a list of some of the other pre-draft visits the Packers conducted, according to NFL sources:

Laurent Duvernay-Tardif, OT, McGill (Quebec), 6-51/4, 321. One of the most interesting players in the draft. Grew up in Montreal speaking French but studied pre-med at English-speaking McGill. Never played high school football but played in a Pop Warner-type league growing up. Practiced once a week during the season at McGill because of his academic responsibilities yet could be No. 1 pick in the CFL draft. Started out as a defensive lineman but moved to tackle, gaining 65 pounds during his stay at McGill. Pumped 225 pounds 34 times during his pro day and is known for playing with a nasty edge. Has been working a fourth-year student rotation at the emergency room in Montreal and served a shift between pre-draft visits.

Prince Shembo, OLB, Notre Dame, 6-13/8, 253. Admitted at the combine he was the one police investigated in a sexual assault case in 2010 in which the 19-year-old alleged victim committed suicide shortly after the incident. He said Notre Dame coach Brian Kelly ordered him not to talk. Didn't deny he had a relationship with the alleged victim, who said she was inappropriately touched by Shembo, but said he was the one who ended their encounter and denied doing anything wrong. No charges were ever filed and the university was criticized for how it handled the incident. Ran the 40-yard dash in 4.66, had a 38½-inch vertical and benched 225 pounds 26 times. Had 191/2 sacks during his college tenure and registered a school-record 17 quarterback hurries in 2013.

Joe Thomas Jr., ILB, South Carolina St., 6-05/8, 227. Ran the 40 in 4.7, registered a 38-inch vertical and did 22 reps on the bench. Was the MEAC defensive player of the year and finished fourth in the running for the Buck Buchanan award for top FCS defensive player. Had 116 tackles (84 solo), including a conference-best 20 for loss, in 2013. Also had 71/2 sacks, an interception and five pass breakups. Played on the nation's No. 1 rushing defense and No. 2 scoring defense.

Beau Allen, DT, Wisconsin, 6-2½, 333. Did an impressive 30 reps on the bench at his pro day and had a 31-inch vertical. Didn't do the 40 because of a hamstring pull. Might be better suited as a defensive tackle in a 4-3 than a nose tackle in a 3-4. Played the latter for one season at UW, his last under new coach Gary Andersen. Had just 10 tackles and 1½ sacks as a nose tackle. Had 13 tackles for loss and 6½ sacks in two years previous in 4-3. Has played at a low weight of 312 and a high of 345. Wasn't invited to the combine but several testing numbers would have ranked high among DTs.

Walt Aikens, CB, Liberty, 6-1, 203. Receiving a lot of interest. Started five games at safety under current Packers assistant special teams coach Ron Zook at Illinois. But got caught up with the wrong crowd and was charged with misdemeanor theft charges for possessing a computer taken from a dorm room. Pleaded guilty and served a two-week sentence. Was suspended from the program and transferred to Liberty. Handled the school's strong code of conduct fine. Ran 4.37 on pro day but was downgraded to 4.49 because of a fast track. Also competed in basketball and track at Liberty. Had a 13 on the bench. Played well at the Senior Bowl. Arms measure 32¼.

Luke Bowanko, C, Virginia, 6-5½, 302. Started his final 37 games for Cavaliers. Ran 40 in 5.25. Did 26 reps on the bench. Has a B.A. in foreign affairs and returned this spring to complete his master's. Is projected as a center but played both left and right guard, including 13 games at RG in 2011.

Brian Dixon, CB, Northwest Missouri State, 5-113/4, 196. Ran the 40 in 4.41, had 14 reps on the bench and registered 30½ vertical. Played at Joliet (Ill.) Junior College with his twin brother, Brandon, then started with him at the two cornerback spots at Northwest. Both were headed to Division I programs (Brian to Kansas State and Brandon to West Virginia), but grades and credit issues forced them to go the Division II route. Brandon is more highly regarded.

John Fullington, G, Washington State, 6-5, 300. Started 43 consecutive games, tied for the longest streak at WSU for an offensive lineman. Started at both right and left tackle as freshman, then played LG as sophomore, LT and LG as junior and RG and RT as senior. Threw the shot put and discus for the track team his senior year. Has good lateral movement for height and got stronger over time, putting up 30 on the bench at his pro day. Still needs to focus on finishing blocks. Ran a 5.39 40.

Andru Pulu, DT, Eastern Washington, 6-13/8, 322. Good athlete with 337/8-inch arms and 81-inch wingspan. Started out as a LB at Washington, but after gaining 50 pounds between freshman and junior seasons moved to DE and then DT. Performed 28 reps on the bench. Ran 5.15 in the 40 and a slow 8.3 in the three-cone. Pleaded guilty to second-degree assault for hitting someone at an off-campus party and spent three months in jail after freshman year at Washington. Was dismissed from the program and transferred. Cleaned up his act and had 43 tackles, 61/2 for loss, one fumble recovery and one pass breakup as senior.

Darrin Reeves, RB, Alabama-Birmingham, 5-67/8, 209. Compact all-purpose back with explosive testing numbers. Ran the 40 in 4.54, scored 20 on the bench, had a 39½-inch vertical and 10-3 broad jump. Rushed for 928 yards and 12 touchdowns for a lousy Blazers team and decided to declare early after receiving a fourth-round grade from the NFL Draft Advisory Board. Is UAB's third all-time leading rusher. Over the last two seasons, caught 70 passes and in 2012 was the only back in the nation with 1,000 yards rushing and 40 receptions.

James Baker, RB, Idaho, 6-0¼, 237. Big, powerful back who for some reason wasn't given the ball much despite very good numbers. Carried 143 times for 593 yards and six touchdowns last year. Added eight receptions for 177 yards and three TDs. In 2012, had 95 carries for 395 yards and two TDs. Ran the 40 in 4.55, benched 225 pounds 27 times, had a vertical of 37 inches and a broad jump of 10-2, all very good numbers for a man his size. Spent first two seasons at a junior college.

Torrence Allen, WR, West Texas State, 6-0, 183. Ran very well at his pro day, posting 40 times of 4.46 and 4.44. Came in at 10-9 in broad jump, hit 40 inches on his vertical and did 15 reps on the bench. Very prolific receiver. Over his junior and senior seasons had 180 catches for 2,702 yards and 20 TDs. Can get down the field in a hurry. Needs to get better at run after the catch. Will need to get stronger, but should have some return ability if given a chance.

Curtis Feigt, OT, West Virginia, 6-6, 307. Grew up in Germany, where he played club football and was able to come to the U.S. under an outreach program for football athletes that allowed him to attend Mercersburg Academy in Pennsylvania for his final two years of high school. Was all-Big 12 honorable mention last year. Started out as a defensive lineman and then was moved to the offensive line. Very raw and still learning his position. Testing numbers aren't that good. Ran the 40 in 5.31, had just 18 on the bench and 27 on his vertical. But scouts are intrigued by his size and his potential to improve with more coaching.

Justin McCray, G, Central Florida. 6-31/8, 321. Played at the same college as Packers G Josh Sitton. Was first-team all-conference last year, playing at both RG and RT. His junior year he played 11 games at RG and two at RT and his sophomore year he played seven at RT and seven at RG. Twin brother, Jordan, started at LG. Ran the 40 in 5.49, did 32 reps and had a 25-inch vertical.

Josh Andrews, G, Oregon State, 6-23/8, 311. Was a three-year starter at LG but may translate into a center. Decent agility but may lack size and power to play effectively in NFL. Ran 40 in 5.03, did 25 reps and had a 29½-inch vertical. Fifth-year senior.

Jeremy Butler, WR, Tennessee-Martin, 6-1¾, 224. Ran the 40 in 4.6 and had a vertical of 36. Performed the bench 15 times. A playmaker for the Skyhawks, he put up big numbers in just two years in program. He finished with 141 catches for 1,953 yards and 20 TDs. His eight 100-yard receiving games ranked first in school history.
