Bust is an overstatement and I am always careful to use that word too soon.
However I think it is more fair to say Oliver, Ford, Epenesa, and Edmunds have all underperformed their draft status. Yes they are all starters and yes Edmunds for a brief 8 or 10 game stretch played like a ProBowler. But for the most part these high draft picks have been at best average to poor. I am still a big fan of Knox (more so than most on this board) but to be fair he has been at best inconsistent too.
He has had some really nice picks too in Gabe Davis and the jury is still out on Moss/Singletary.
