He did.

This is basically the inverse to what I just wrote. Mike Freeman of CBS Sports on why Chip Kelly is wading through dangerous waters (that’s a phrase I’ve always wanted to write– wading, who wades these days?!):

But there is a danger here. Kelly had better be careful because coaches better than him have tried this, and coaches better than him have failed.

Kelly is putting himself inside a tight box. If he doesn’t win quickly, the doubts will arrive fast, coming from inside the locker room that won’t forget how he demoted players in OTAs.

The NFL is littered with the burned-out carcasses of the motivators and the game-changers and the new minds. Steve Spurrier left the Florida Gators for Washington and is now a cautionary tale. Nick Saban is quite possibly the best defensive mind that college football has ever seen, and he couldn’t make it in Miami. Bobby Petrino was so humiliated in Atlanta after leaving Lousiville for the Falcons job, he informed Falcons players he was quitting via a four-sentence note left in their lockers.

DeSean Jackson seemed to take his practice demotion in stride. Michael Vick? Not so much.

Maybe we’re all just so enamored with a coach who does things differently that we’re a bit blinded by the dangers of such a thing. What if this all backfires? What if the players hate Kelly and turn on him the way they turned on the media and fans the last few years? This can be kind of a vicious group. What if Kelly’s system is so ridiculous and becomes such an epic failure that it’s spoken about in lore twenty years from now by guys who speak in war metaphors and eat glass for breakfast? It could happen. I don’t think it will… but it could. Let’s just tuck that away in the back of our minds.
