That's proving to be the case less than halfway through UNC's spring practice period as the 6-foot-3, 200-pound signal caller is splitting second-team reps with red-shirt freshman Kanler Coker.
"I think it's a great battle right now," UNC head coach Larry Fedora told reporters following Wednesday's practice. "He's come a long way in just a short period of time. He ought to be worried about his dance this Friday night back in Mentor instead of worrying about going down and scrimmaging in Charlotte. The kid's come a long way. Every rep he's getting, he's getting better."
During the media portion of practice on Wednesday, offensive coordinator Blake Anderson spent a significant amount of time in one particular quarterback drill working with Trubisky on his footwork.
"He looks great," Renner said. "For coming in as supposedly a senior in high school, he's doing above and beyond what I thought. He's looking really good throwing the ball to catchable spots for our receivers. He's making all of the strides and is really pushing Kanler right now."
When asked about Trubisky's best qualities, Fedora promptly mentioned his arm strength before adding, "I'd say it would be how quickly he's picking things up, because he's doing a fairly good job of managing the offense right now."
Renner referenced the freshman's movement in the pocket.
"His ability to step up and make plays with his feet when the throw's not there is a big factor they're looking at right now," Renner said.
Trubisky earned Mr. Football honors in Ohio after passing for 4,063 yards, running for 899 more and totaling 60 touchdowns in his senior season at Mentor.
Red-shirt sophomore quarterback Marquise Williams, who served as Bryn Renner's backup in 2012, is currently suspended for undisclosed reasons but is expected to rejoin the team this fall.
