nfl website is reporting Cassel has been tagged. His salary (and cap hit) would be 14.65 million. compare this to brady whose cap hit this coming year is 14.62... That means the pats would have almost 30mil tied up in QB's. And the cap for this coming year is just over 129 million.
They would have 25% of their cap room tied up in two guys, who can't even play at the same time (or even on opposite sides of the ball)
They must not have a lot of faith in brady being back healthy..
