Hindsight is 20/20. There were plenty of fair weather fans who wanted Reich and later Collins to start ahead of Kelly at times. After Kelly retired, the Bills had two different QBs make the Pro Bowl while playing for them. They were both run out of town.
Edwards showed he had the stuff early last season until he got hurt. Maybe he recovers, maybe he doesn't. But judging him while he was forced to run that abortion of the K-Gun with no offensive line is not fair IMHO.
