Except when he did fill in when injuries occured to some Bills WR's, he actually looked halfway decent doing it. He also occasionally was used as a punt returner.
Its not a perfect comparison, but it's not a HORRIBLE comparison because both Tasker and Hill were both "utility players" used at different positions. Its just Hill has excelled at more positions and has more yards on offense then Tasker did.
BTW, Tasker had arguably a HOF-caliber career yet your histrionics make it seem like he sucked or was a one-dimensional player. He wasn't and he was a very good utility position player for his time and era.
