I think he's better in pass pro, could be wrong.
I guess I'm thinking of Singletary's notable drops, and I remember Moss having a couple good receiving games mid-season. I just went back and looked at his receiving stats and between weeks 5-8 he had most of his production including a 6 for 39 and 3 for 55. I formed a positive opinion of him as a receiving back at that point even though it didn't continue, I remember being pleasantly surprised.
