In defense of the fans, there's more to it then the "scheme didn't work". Part of the fans' frustration is that he turned a very good running o line into a wet paper bag. It may not have had anything to do with scheme, but rather his actual coaching. The line never got better as the season progressed. In fact, they seemed to get worse. Blame goes to the players as well; but clearly, Castillo sucked. But now, if they have all of these other pieces in place, there will be continuity, which should result in better play on the field.
