A very long, highly eventful, borderline controversial, and nonetheless fascinating offseason for the Buffalo Bills comes to a semi-official close this evening. Sure, the 2015 season unofficially began when training camp opened on July 31, but now we're onto the next step: the Bills playing under the lights at Ralph Wilson Stadium. It may only be preseason football, but it'll be fun, anyway.
Tonight's preseason-opening opponent: the Carolina Panthers. All eyes will be on the Bills' quarterback competition - Matt Cassel will start, followed in succession by Tyrod Taylor and then EJ Manuel - but there is plenty of other stuff to keep track of, too.
