Usually... not always. Just look at Jerry Hughes... Colts couldn't wait to get rid of him. Sometimes a player just needs a change. For me Perriman and Foster are same type of player big tall fast receivers who can't catch and tracks balls poorly. Only difference is Breshad has 1st round talent and his potential is much greater. The way I see it is worst case scenario he gives us the same production that Foster would give us and best case scenario he lives up to his hype after leaving Baltimore. I'd do that every day.
And obviously they don't disagree with me or they wouldn't be working him out or made that trade for Coleman.
