Rex Ryan's arrival in Buffalo certainly sparked optimism about the NFL's No. 4 ranked defense remaining among the cream of the crop.
The buoyancy is also shared on the offensive side of the ball, where the Bills stable of backs is excited about the prospect of Ryan bringing a ground-and-pound style to Western New York.
Speaking on NFL Network's The Aftermath on Monday, running back C.J. Spiller gushed about Ryan's style.
"It strikes me well," Spiller said. "That's what I love to do is run the football. And Rex, that is what he's known for, running the football, being physical, playing that hard-nosed football. I'm excited about it. This is a great opportunity for us to get this thing turned around. We ended this season on a 9-7 record, now it's just time to build on that and get into the playoffs."
Spiller, of course, is a free agent and might not be around to take advantage of Ryan's ground preference.
NFL Media Insider Ian Rapoport reported that Ryan would bring former San Francisco 49ers offensive coordinator Greg Roman to Buffalo.
After seeming like a fish out of water in Doug Marrone's offense, Spiller, if he returns, could be in for a revival under Ryan and Roman.
