I see this coming up a lot in other threads, and it irks me enough to make a post about it. People think that other teams will give the Pats equal value for Tom Brady; this brings me to my point:
EVEN IF THEY CHOSE TO TRADE HIM (which they won't) THE PATRIOTS WILL NOT GET EQUAL VALUE FOR TOM BRADY. EVER.
There is not enough talent (players), or prospective talent (draft picks) on any team to replace Tom Brady. Tom Brady, by himself, makes your team a playoff contender every year. With some additional talent, you become a Super Bowl contender. With a good deal of help, you get yourself a dynasty.
Current Talent:
Brady gets paid, what, 14m/yr? There's no way you can get 14m of players to equal Tom Brady's talent. If you got enough talent to match Tom Brady, there's no way it would cost 14m/yr. Try more like 40m.
Prospective Talent:
Name me a draft class (yes, an entire 7 rounds of players) in the past 10 years that have had the effect on their team that Tom Brady has had on the Patriots. And, thats looking in reverse. If you could have any one team's entire 2009 draft for Tom Brady, would you take it? I sure as sin wouldn't.
In short, you will not get equal value. When you have a player like Tom Brady, you keep him. You pay him. You win with him.
