We all love rooting for an underdog. Often times, we let that get in the way or objectively evaluating talent.
Let's face it. Brandon has not been the same since his knee injury. And, unfortunately for the Skins, he manages to run a PR/KR for touchdowns during the pre-season... which gets him on the 52 man roster.
Frankly, he is a one trick pony, and doesn't have the speed or power to get a decent run. I would cut him asap, and let Santana Moss handle PR/KR duties.
