Buffalo Bills coach Rex Ryan has said that he is yet to decide on who will start the new season as his number-one quarterback.

The Bills have signed both Matt Cassel and Tyrod Taylor in the close season, and they will compete alongside EJ Manuel for a starting spot.

Ryan told WGR-AM: "It's going to be open. It's a competition and whoever earns the job will be the guy that's out there. We have some talented guys and we'll see what happens.

"You bring in a veteran like Matt Cassel. He's done some pretty good things in this league. He's got that veteran presence about him. With EJ back there just going into his third year I really believe EJ is going to improve with his fundamentals having [quarterbacks coach] David Lee here.

"I love the fact that he's a gym rat and he's smart. With our offense being multiple we'll be able to get out of bad plays, so the mental part of it all of the quarterbacks we have should be able to handle that."

The Bills finished with a 9-7 record last season, failing to make the playoffs.
