Chicago Bears

Biggest Post-Draft Weakness: Secondary

Trading up for Mitchell Trubisky means the Bears failed to address a need with their first pick; they just divided their quarterback reps. Despite 57 defensive backs being taken in the draft, the Bears only took one, an injured safety. Eddie Jackson (Alabama) is considered to be a versatile player and exceptional talent when healthy, but the Bears needed to add at least one cornerback in this draft if they were going to feel comfortable with their secondary moving forward.

Prince Amukamara has starting talent, but has been let go by the Giants and Jaguars over the past two seasons because of poor play. He and Kyle Fuller, whose fifth-year option the Bears recently rejected, will be the starting tandem, while Bryce Callahan is the favorite to play the slot. The Bears don't have great starters, but those starters aren't under threat. The only real competition will take place behind Amukamara and Fuller, where Marcus Cooper and Cre'Von LeBlanc are most likely to push for playing time. Not having quality starters is bad. Not having competition for those starters is potentially disastrous.

Notable undrafted free agents: Franko House hasn't played football since high school. Instead, he spent last year averaging 13.4 points per basketball game for the Ball State Cardinals. House is a 6-foot-6, 250-pound project whom the Bears had previously worked out as a tight end prior to the draft. It's unlikely that House makes the roster this year -- it would be a surprise if he even made the practice squad -- but if he impresses he could earn opportunities down the road to eventually carve out a career like others have before him.

Placekicker Andy Phillips set a record at Utah with 84 made field goals. He made NFL.com two years ago with a nifty field goal in practice. More importantly, he nailed all four of his 50-plus-yard field goal attempts in college. In the past four years, Bears kickers have gone 11-of-17 from 50 yards or more.

Detroit Lions

Biggest Post-Draft Weakness: Defensive End

The Lions have enjoyed a smart offseason, rebuilding their offensive line in free agency and adding potential starters at different levels of the defense during the draft. Jarrad Davis should start at linebacker from Day 1, bringing an immediate upgrade to the front seven. That front seven, however, still needs to figure out who will play across from Ezekiel Ansah. Seventh-round pick Patrick O'Connor and low-level free agent Cornelius Washington were the only additions after Devin Taylor left in free agency. Taylor could still be re-signed, but in an ideal scenario the Lions would have upgraded on him this year.

Notable undrafted free agents: Running back Tion Green was reportedly given a $10,000 signing bonus to join the Lions as an undrafted free agent. The Lions have a variety of running backs who can fill different roles, but Green's size will give him a chance to carve out a role on special teams before challenging for short-yardage opportunities on offense.

Speaking of big-money UDFAs, Detroit guaranteed $36,000 to San Diego State defensive end Alex Barrett. Barrett was one of four rookie defensive linemen the Lions added after the draft, along with UNLV defensive end Jeremiah Valoaga, Mississippi State defensive tackle Nick James, and Auburn defensive tackle Maurice Swain, Jr. Valoaga only played 16 college games due to injuries and off-field troubles (he was kicked off the team last year for a violation of team rules -- what happens in Vegas, knocks you out of the draft), but had six sacks in ten games last year, and has plenty of room for growth in his 6-foot-6, 255-pound frame. James has his own off-field issues -- specifically, four arrests in his college career, most alcohol-related. But he is 6-foot-6 and 330 pounds, and athletes that size are worth the risk of a UDFA contract. Swain, meanwhile, offers almost as much size (6-foot-5, 314 pounds) and much less drama.

Green Bay Packers

Biggest Post-Draft Weakness: Running Back

The Packers took three running backs in the 2017 draft, but none were selected before the fourth round. Ted Thompson spent his first four picks on the defensive side of the ball, passing on some top-tier running back prospects. Christine Michael's release means that the Packers will enter next season with Ty Montgomery as their only veteran running back -- and calling him a veteran is a stretch since he has been a running back for less than a year.

Jamaal Williams (BYU) was the highest selected running back of the rookie trio, so he will be the favorite to back up Montgomery. In theory, Williams will be a good complement to Montgomery because he is a big-bodied ballcarrier. The concern is that he lacks the vision and dynamism to be more than just a sporadic contributor. The Packers might be able to get the most out of Montgomery and Williams by using them in specific situations, but the lack of versatility and experience at that spot remains a major concern.

Notable undrafted free agents: The interior of the offensive line for the Packers is going to be a focal point during the leadup to the season. With Josh Sitton and T.J. Lang now playing elsewhere, there are opportunities for younger players to win jobs. Adam Pankey (West Virginia) isn't going to be a starter, but he was a surprise UDFA. Pankey lacks lateral athleticism, but has impressive size and power. A good training camp could see him earn a roster spot.

Miami punter Justin Vogel could challenge incumbent Jake Schum, who failed to make the top 20 in either gross or net average last season. The Packers also have one of the nation's best underdog stories in BYU quarterback Taysom Hill. Hill was often injured in his time in Provo, and after spending five full years with the Cougars and two more on a Mormon mission to Australia, he turns 27 in August. He is one day younger than Randall Cobb, who just finished his sixth season with the Packers. Hill completed less than 60 percent of his collegiate passes, but he ran for more than 2,800 yards.

Minnesota Vikings

Biggest Post-Draft Weakness: Wide Receiver

Dalvin Cook was a somewhat surprising selection for the Minnesota Vikings in second round of the draft. Cook's value at that spot must have appealed to the Vikings, because they could have easily waited on the running back position with Latavius Murray and Jerick McKinnon on the roster. Cook was the only skill-position player the Vikings took before the fifth round, when they added two rookie receivers. Those two rookies will join a crowded receiver depth chart that lacks a true third option to rely on. Ideally, the Vikings would bring in an established veteran to compete with Laquon Treadwell for that spot. Anquan Boldin is still available.

Notable undrafted free agents: The quarterback depth chart is always a focal point for every team, but that is especially true for the Minnesota Vikings. As Teddy Bridgewater's status remains unknown, the Vikings will be searching for a backup for Sam Bradford. Case Keenum is the favorite, but he shouldn't be guaranteed his job. Wes Lunt (Illinois) should get plenty of opportunities through the offseason and into the preseason. According to Lance Zierlein of NFL.com, Lunt possesses an NFL arm and can make all the throws with a quick release. His time in college and in high school was marred by constant health issues.

The Vikings guaranteed at least $20,000 each to a trio of defensive free agents: SMU cornerback Horace Richardson, LSU defensive end Tashawn Bower, and Southern Miss defensive tackle Dylan Bradley. Richardson's NCAA career was marred by a pair of ACL tears. Bower only had 5.5 sacks in his career, but three of them came in his final game against Louisville's Heisman Trophy winner Lamar Jackson in the Citrus Bowl. He was recruited to LSU in part by Danielle Hunter, who also played a role in convincing Bower to join the Vikings. Bradley, the nephew of 10-year NFL vet Jason Hatcher, led the Golden Eagles with 15.5 tackles for loss and 8.5 sacks last season.
