I just saw that Isaac Bruce only weighed 173 when he was officially weighed. As you know Harrison was 175. I quick search showed Hilton was 183 and Clayton was 176. I'm sure if we really dug, we'd find a ton more of receivers in that 175-185 range.
His weight is actually starting to be less and less of a concern to me. If you can get open, the rules these days totally protect smaller receivers.
I think with todays NFL you need both big bodied and quick twitch wr's. I think the quick twitch wr's are imperative between the 20's and the big bodied receivers do better damage in the red zone.
We have the big bodied possession receivers, its time to add the quick twitch.
