Geno Smith is widely expected to be the top quarterback selected in the 2013 NFL Draft.

But NFL Films' Greg Cosell also has concerns about Smith's "slow eyes."

"When you watch a lot of film, you know what the route combinations are, you know where the ball is supposed to go based on the defense, and you know when a throw is there," he explained. "And too many times I thought that throws that were there clearly defined, he took an extra beat.

"And in the NFL, that will kill you. You can still complete balls in college like that, but that won't happen in the NFL. And I can't answer whether that's coachable or not."
