He was an elite #1 wide receiver when the Eagles traded for him from the Titans. Two years later the Eagles want to dump him? Why? Because Brown is not elite anymore according to Roseman the GM of the Eagles (who is a better talent appraiser than you with a lot more insider information than you).
Brown has lost a step. The Eagles know that and are dumping him. We will see.
This is true, but if the Pats do not trust their draft management, they should change the management, not pick up WRs who have lost a step.
