AR reminds me a lot of JaMarcus Russell, except he had a less impressive college career. There were lots of warning signs about JR but at least he was a good college QB.
When commentators are asked what is the most impressive thing about a player, and the answer is something that sounds superficially impressive but actually doesn't have anything to do with playing the position, it's a huge red flag. The thing from the pre-draft process I heard the most about AR was him hitting the ceiling of UF's indoor facility during his pro day. The "most impressive thing" about JR during the pre-draft process was him throwing the ball 70 yards in the air from his knees at his pro day. Those are cool party tricks, but does it mean he'll be great at playing the position in the NFL?
