—In terms of mechanics, accuracy, footwork and touch, he's the best passer in the 2018 draft class. He's an incredibly clean passer.
—Rosen's background as a tennis player is obvious in watching him take a three- or five-step drop.
—He's a prototype in his release and delivery and operates like an NFL quarterback on play action.
—Rosen doesn't get rattled in the pocket despite a thin frame and tends to get better the more he's hit.
—With little talent around him at UCLA this season, Rosen's numbers weren't off the charts. Drops and missed connections played a role too.
—He has the arm strength to hit windows and has shown consistent touch in leading receivers upfield. He doesn't miss often.
—Injuries and a lack of mobility combine to scare teams as much as Rosen's alleged personality quirks.
—He has been injured in each of his three seasons at UCLA and missed a large part of 2016 with a shoulder injury.
—He doesn't have the athleticism to evade pass-rushers and instead puts down roots in the pocket.
—When asked to move off his spot and make plays, his accuracy suffers.
—Rosen will be judged on his off-field decisions. He infamously wore a "F--k Trump" hat to a Trump golf course and had a hot tub installed in his dorm room.
—Scouts have told us Rosen is well-liked by teammates but not by coaches due to his "smarter than" attitude.
GRADE: 7.15 (Round 1)
PRO COMPARISON: Jared Goff, Los Angeles Rams
Rosen is a polished quarterback who is ready to take over an NFL offense. He is a clean prospect in terms of mechanics but has the biggest question marks when it comes to injury history and coachability.
