So... I'm not convinced. This isn't an attack on Flemming, but I don't know how good he is. People have talked about how awesome a player he is for a long time. He's got 2 catches for 18 yards, and once drew a pass interference. That's the stat line. He's had a lot of injuries.
It's a good story for him to recover, come back, and be productive next season, but if we trade the chance to bring in a talented 4 year player for that one season... I would take a chance on the 4 year player, especially given the way that it looks like our recruiting is winding down. I'm comfortable being guilty underestimating his value to the WR position.
