By my best guess, the New England Patriots have 1-2 more seasons of being relevant. As soon as Brady retires, they are going back to the 1970's and 1980s in terms of success. Belichick won't stick around long when it's obvious the team is on the way down. He'll exit too.
In other words, about the time POPs becomes a full time STEELERS fan !!!
If he wants to cement himself as a master without Brady and cheating, he takes a head coaching job someplace else and makes them a winner.
The company I work for is based in the suburbs of Boston. I have to go up there 1-2 times a year. You just can't understand their audacity or acceptation of cheating among the locals until you see them talk about it in an unfiltered conversation.
