What’s the point of making this into some huge deal? It probably won’t happen; if it does happen, whatever...
When Joe Montana went to the Chiefs, I’m sure many, many Niners fans rooted for him. Such slim odds that the two teams will play in some elimination game like the Super Bowl anyway. It’s pretty easy to remain a Patriots and (no longer a Patriot) Brady fan, provided he doesn’t pull a Brett Favre type of move. Nothing about the way Brady’s handled himself would suggest he’d do something like that, and for business purposes alone keeping his New England legacy in tact is a wise move. Favre had egomaniac tendencies all along.
I would think this would be like a Michael Jordan/Wizards situation if you were a Bulls fan. I mean, there’s nothing left to accomplish or prove. He is forever the face of the Patriots franchise, just like Jordan is in Chicago. One day there will be a statue of TB12 outside Gillette.
