Cary Williams didn't care for the system of Chip Kelly during his time playing for him with the Philadelphia Eagles.

Williams' gripe was that Kelly's revolutionary practices, which include a rigorous amount of conditioning, don't really work. He said his current team has the right idea and that players need to be better rested.

"We was talking about the fact that our conditioning and things like was going to kick in because we worked harder than everybody in the National Football League with the Chip Kelly thing," he told 710 ESPN in Seattle. "We got out there, we got our teeth kicked in. So all that conditioning didn't necessarily work. Preparation wasn't necessarily the greatest neither that week. When you're going up against teams that prepare well, practice well, coach well, it's difficult in games like that. I think towards the end of the year we were exhausted and we got outcoached the majority of the games."
