Josh McCown is open to joining the Bears as the backup to starting quarterback Jay Cutler. Chicago is looking for an experienced reserve to place behind Cutler. "I understand right now there's not anybody beating down my door to be a starter," McCown told ESPNChicago.com. "So understanding that, where do you go to be in a great situation where you are a backup? For me, in Mike Martz's offense and where I'm at in my career, I feel comfortable with [coming to Chicago]. The fact that Jay [Cutler] is there doesn't affect me at all, and probably gets me more excited because you get to work with a guy that talented, and hopefully help the coaches get the best out of him. "The commitment they have to Jay, there's nothing you can do coming in to get on the field. So for me, my motivation would be to come in and help him be the best he can be, but also get myself ready so if anything happens to Jay, I would be able to help the team win games."
