Looking back at at Kelly's first year is, IMO, glorified hindsight. Sure, you can say you knew he was going to be good because the guys in the hall of fame now. I'm sure if you ask any fan they'll all say "yea, I definitely saw the talent." And seeing as the internet wasn't around back then, we have no way of disputing that.
There were legitimate fans calling for Reich to start in his first couple years, so obviously it wasn't consensus with his talent by some fans.
