Up until 2013, Chip Kelly's success has been on the college level.
His teams at Oregon went 46-7 during his four seasons as head coach.
There has been talk about Kelly’s methods and how unique his offense is, but he insists that there's nothing special about how he goes about things and that teams like the San Francisco 49ers and Seattle Seahawks have had good results behind similar schemes.
Kelly says anything he has in his program is for a reason and that putting in the work is the key, not a magical scheme.
"We don't do things just for the sake of doing things. This isn't change for the sake of change. This is change that we believe is necessary, because we believe in what we're doing and we've got evidence to prove that it's going to work," Kelly said, via Martin Frank of USA Sports.
"It's to get them to understand if we're going to do something, there's an importance to it," Kelly said.
"If there's an importance to it, then we should be able to explain that to you. Not just do it because we said so.
"We're under his leadership," wide receiver Jason Avant said. "We're going to do everything he tells us to do. Veteran or not, everyone respects him the same."
