Without getting too much into specifics, it feels like there has been a seismic shift in philosophy. Before training camp Harbaugh talked about a wide open competition and the guys who step up will make it, regardless of past history. I forget the exact words, but I like the concept. Butler's release doesn't really jive with that philosophy, but its not exactly like he was a potential pro bowl WR either. I think they're shooting for identifying real explosive game changers, cause last year didn't cut it obviously.
