I was reading a story on WEEI this morning: https://weei.radio.com/blogs/ryan-hannable/what-are-the-details-of-tom-brady-s-contract and it got me to wondering about this line: "the Patriots can sign him to a new contract at any point — they have the exclusive rights to negotiate with him up until March 16." But Tom Brady is still "under contract" for another year. That extra year just happens to automatically void on March 18th. We have been told many times that per the CBA, someone under contract cannot renegotiate that contract until after a year passes after the old contract is signed. Brady signed this latest contract last summer, well after March 18th. How can the Patriots negotiate with Brady under these conditions? Can any CBA or cap gurus help me here?
