Arm strength will be a "significant concern" for USC QB Matt Barkley as he transitions into the NFL, according to NFL Films' Greg Cosell.
Cosell mentions his other concern is Barkley's mobility. "He's not very athletic in and around the pocket," Cosell adds. "Functional mobility is a bit of a question... Barkley is going to need to be a rhythm quarterback with great timing, great anticipation, great ball location. That will have to be his game if he is going to be a quality starter."
