Raridon doesn't look nearly the same like he did when he was healthy in high school. Not only is he not nearly as fast on his feet, but his hands look slower, too.
The pass that bounced off his hands during that last drive against Miami would have easily been caught by his younger self.
His situation reminds me of how James Aldridge turned out. He was a 5 star RB, but had a couple of nasty injuries his senior year, and never could crack the starting lineup while he was here. The fact that Armando Allen, injuries and all, stayed ahead of him the whole time shows how bad that injury was.
