This really isn't worth commenting on. Is this anything we don't already know? If McGinest doesn't restructure, he could be cut. No sh!t. He's been in this position before, and has renegotiated each time. Willie should be concerned with two things right now, earning more rings, and enhancing his HOF chances. Both of those are best accomplished with Belichick.
When Brady's last year of his contract gets here, he can write the same thing. If Brady's contract isn't renegotiated he could be a free agent.
In fact you could take any player in the NFL, write "could be a cap casualty" and be right. And I could be the next Mr. Jessica Simpson. And could be the #1 pick in this years draft. And could have already won 10 million dollars in the Publishers Clearinghouse Sweepstakes.
