Dallas moved Ribiero specifically to make room for signing a guy like Benn. Without grossly overpaying for him, Dallas would match.
Dallas did that because Ribeiro wasn't going to re-sign there and they also got a young center prospect back. They also have Glennie and Derek Roy, Jamie Benn is more comfortable at wing. It could be said they moved Ott to accomodate Benn could it not?
