Rob Ryan is a free agent coach and his brother, Rex Ryan, was asked if they might work together with the Buffalo Bills.

"A lot of things have to (happen)," Rex said Tuesday. "I mean, I'll never say never, that's for sure. We've kind of purposefully set a path going to different teams. He's his own man, I'm my own man, and we've purposefully set that path.

"With that being said, I ain't gonna lie to you -- I think it would be pretty fun. If it could help, obviously you consider it, but he would have to consider it as well. We got great coaches already here, and so ... but we'll see."

The Ryan brothers were assistants for their father, Buddy Ryan, in the 1990s with the Cardinals.
