It’s always tough to determine what makes a player a sleeper or a bust during the preseason. JJ Watt was being drafted as a top 10 DL last year, but he finished as the #1 DL by a wide margin, so did that make him a sleeper? Jared Allen, on the other hand, was typically the first or second DL off the board, yet finished at DL16 for the season, so did that make him a bust? This question is best answered by looking at opportunity cost.
