This is an interesting article where the author basically ranks players by their trade value in the current situation while factoring in their age, salary etc Here is the LINK Here are the top 5 players as ranked by this article 1. Aaron Rodgers 2. Tom Brady 3. Drew Brees 4. Andrew Luck 5. Eli Manning Basically what these rankings say is If Pats decide to trade Brady it should ONLY be for Rodgers ,and Rodgers is the most un-tradable player in the NFL. Simply put NO TRADE IS WORTH IT....... I am surprised Megatron didnt make it to the top 5 .
