The NFL draft is all about ascertaining whether the player you're looking to draft will be more of a risk or a reward to your organization. There are some cases, though, where that can be really difficult to determine, particularly with players like David Amerson, a cornerback who can alternate between dizzying extremes.
For his 2011 season, Amerson recorded 13 interceptions, which tied him for the second most in NCAA history. At times he's shown himself to be a turnover machine that can make plays out of seemingly nothing.
Then there was his disappointing senior season, which included a low point where he was beaten for four passing touchdowns in one game. It was a rough year that saw his interception output drop down to five, and it also saw him get burned for long receiving touchdowns far too often.
When he's on his game, Amerson has the potential to be as good as any cornerback prospect in the 2013 NFL draft.
