Rob Johnson. Great QBs come in and make plays and win games. Weak QBs don't. Look at Brett Favre, Tom Brady, Darryl Lamonica, etc. they were all in their second years and look how they did. I hate to say it. I don't see it with Losman.
On a different note, there was another former Tulane player (M.Moore of the Vikings) who said Losman is a horrible team player. It this his problem with the Bills?
