I say move the Browns across the pond, or create a completely new expansion team.
as for Brady, if it was me and that was my team I've always played for - to me (and this applies to anyone ala Gonzalez, Montana, Manning, etc) it would be the respectful and honorable thing to do to stay, take a huge pay cut that allows your team to move forward (you already have a sh,t ton of cash anyway) and gracefully be the mentor to the next QB. You honor your team, your coach and your fans and most importantly - your position. Plus the team has a kick ass back up...
