Should the NEPatsies trade TOM BRADY???

First, i am aware of TOM BRADY's status as one of the premier QB's all-time in the NFL. And he is hurt and less mobile + MATT CASELL is a free-agent at the end of this year and has quick-feet and has maturated into a #1 pick!!! WILL THE NEPatsies spend millions-make that gazillions for him to be a back-up??? WILL CASELL WANT TO BE A BACK-UP TO BRADY??? WHY NOT TRADE THE DECIDELY LESS MOBILE BRADY WHILE THEY CAN TO GET 'QUALITY PLAYERS' FOR HIM AND RETAIN THE YOUNG-GUN CASELL??? Just a thought - probably will never happen - but will the NEPatsies just let CASELL go the free-agent route and 'bank' on BRADY returning to 'form' with no after-affects???
