Josh Rosen is widely regarded as the most mechanically sound quarterback in the 2018 NFL Draft. He’ll need to justify the hype at the Scouting Combine, but the primary concern with Rosen has nothing to do with his ability to play the position.
If the UCLA Bruins star is going to solidify his place as the best quarterback in the 2018 NFL Draft, then he’ll need to prove that his core strength isn’t an issue.
Rosen has a thin frame, which has caused some to question if he can remain healthy in the NFL. The durability concerns date back to his college career, as he was active for just six games in 2016 due to a shoulder injury that required surgery.
Rosen also missed time in 2017 due to concussions, which calls for an even higher degree of discomfort with his health moving forward.
What Rosen can do to address the shoulder injury is prove that he still gets great velocity behind his throws. What he can do to temper the criticism about his overall durability is show up and prove that he’s adding muscle mass to his frame.
This is more of something that he should have been doing since the end of the 2017 season, but if Rosen is still as thin as before, that alone would be a reason for skepticism.
