I'm with Bako on this. I seriously doubt the players suddenly totally abandoned warming up, something ALL of them have done since Peewee football, once Dennis Allen took over. I think it would probably be more likely that they were expected to have warmed up prior to taking the field for practice as opposed to an organized warmup session as the first step of organized practice. Could this have allowed some players to cut corners in their preparation before hitting the field? Possibly so. I know for at least home games all players are out there on the field going through pre-game warmups. I can't speak to practice, however.
