There's a chip on Kyle Bolin's shoulder, but that didn't stop him from slinging even the most difficult throws that his new trainer dialed up.

If anything, that might be helping the newest Rutgers quarterback on each throw he makes.

"He has a chip on his shoulder in all the good ways," Tony Racioppi told NJ Advance Media. "He wants to prove people wrong. He wants to be the guy. He has the charisma -- that edge to him -- that when he walks into a room he has a presence."

When Bolin -- a one-year graduate transfer from Louisville -- arrived in Piscataway last month, he sought a trainer for the time before he is allowed to work with Rutgers offensive coordinator Jerry Kill under NCAA rules.

Former Rutgers players that he crossed paths with recommended Racioppi, a former Division III two-time All-American quarterback at Rowan who is a trainer with TEST Football Academy and a high school football coach. The two connected and held their first private workout Wednesday.

"The first time you work with somebody you want to see them do everything and see what their strengths and weaknesses are," Racioppi said. "I think he's a great rhythm thrower as far as three-step drop and five-step throws. He's always in rhythm and in balance."

The workout inside the Rutgers practice bubble included about 35 minutes of mechanics drills before switching to throwing routes and going through receiver progressions.

"Kyle ran a very sophisticated pro-style offense, so you can tell from a schematics standpoint and a coverage standpoint that this kid has been coached," Racioppi said. "He is very sharp. He is not a kid who gave a hand signal or two and went on his way. He understands concepts."

Bolin's targets Wednesday included 3 with NFL ties: Former Rutgers receiver Carlton Agudosi (Arizona Cardinals), Oakland Raiders tight end Ryan O'Malley and former Indianapolis Colts signee Andrew Opoku.

"I like the fact that he has good anticipation," Agudosi said. "He gets it out of his hand before I make my break. He does a good job getting it out there because if it's too late a ball could be picked off or a hard catch."

Bolin threw for 2,104 yards and 13 touchdowns with 10 interceptions in 16 career games at Louisville, including six starts before he lost the job to 2016 Heisman Trophy winner Lamar Jackson. At Rutgers, he will be in a three-way training camp battle to be the starter.

"He throws the layer ball very well, which is that second level over the linebacker in front of the safety," Racioppi said. "In my experience, a lot of kids can throw the hitch, slant, drive throws. Anybody can throw the deep ball, for the most part.

"Where guys are weak is on the second-layer throw. That's such an innate feel thing. It's hard to teach. You have to be born with that or it's a repetition thing, and he has that."

Racioppi coached Agudosi at Franklin High School and helped train him and fellow former Rutgers receiver Andre Patton (San Diego Chargers) for the NFL earlier this year. He also worked with former Rutgers quarterback Philip Nelson at TEST.

"Before we threw, we sat and talked about football," Racioppi said. "I hit a lot of boxes with guys -- everything between being a star, not being a star, transferring (from Tennessee Tech) and having a shot in the NFL and then not -- so we connect."

Agudosi played with five different starting quarterbacks at Rutgers, so he knows the many different looks.

"It was a short period of time," he said, "but from what I've seen (Bolin) has all the intangibles as a quarterback: Great feet, a live arm, he could take coaching. I saw him fix a few things immediately."

Rutgers' competition includes Giovanni Rescigno -- who was No. 4 on the depth chart at this time last year but quickly ascended to start the final five games over healthy bodies -- and highly touted true freshman Johnathan Lewis.

Bolin was an unexpected late addition to the battle after veteran backup Zach Allen was injured during spring practice.

"I was very impressed with his footwork and the fact that he can go to a primary (receiver), reset himself and go to a secondary receiver, or to an outlet guy or third option on a progression," Racioppi said. "I had him scramble and set up. I think he's an above-average athlete."

While neither Wednesday's workouts nor the 7-on-7 passing drills that Rutgers players organize themselves in the offseason include a pass rush, Racioppi designs workouts to simulate the game experience.

"Kyle has a NFL arm and he moves really well," he said. "If somebody misses a block, he could escape that. In college football today, you have to be able to make one guy miss, reset yourself and be able to throw."
