Well...While I don't disagree that Brown had a really disappointing year, he may very well have been the most effected Bills Defender by Ryan coming to town...
The move from WLB in Schwartz 4-3 where PB thrived, to MLB in Ryan's...whatever it is...just killed his progression...Brown was playing out of position and asked to be the field leader for a Defense he was struggling to learn...I don't think there is a snowballs chance in hell that Preston is back at MLB for this Defense next year...
IMHO Preston Brown did not forget how to play football...The same way Mario, Dareus, and the rest did not forget...Rex came in, blew up a good thing, and what's left in the wake is an absolute ton of questions going forward...
