It’s not hard to miss just how easy it is to dismiss Josh Reed, the second-year wide receiver, and a short guy who will play a big role in determining the success of the offense. A former second-round pick and the Bills’ No. 3 wideout in 2002, Reed has to fill big shoes, but seems more capable, at least from a physical dimension, of fitting into a pair of ballet slippers, rather than the clodhoppers the departed Peerless Price left behind.
