Purely because we gave up so much for him, he has so much potential, and he delivered so much less.
The fault really wasn't his. It was whoever bought into the notion that there was a place for a gadget player in a Fisher offense, compounded by whoever gave him that second contract.
I agree that Reynolds is over rated. He'll never be more than a rotational WR and will continue to deliver disappointing moments at the wrong time. Some team will sign him away with an over-inflated contract then he'll bounce around the league on multiple teams.
