Mehhh... Give me Swann. And I HATED the Steelers.
He played before the steriod era thus didn't play as long and amass the career stats. Nevertheless he was absolutely the best in the game. There simply weren't any DBs athletic enough to stop him. The same can be said for Moss.... conversely Swann was at his best in the big games, won multiple Super Bowls, and MVPs. Obviously, Moss won't be remembered as champion and many would call him "me first."
Frankly Rice wasn't that athletic. He was the beneficiary of the crazy numbers from the West Coast offense and his very, very long career. Swann played for a run first team (that obviously could pass also). I'm not poo pooing Rice's abilities. He was an all time great, but he wasn't quite the incredible freak athlete among teams full of incredibly athletic guys.
Ahmad Rashad wasn't far behind IMO. Those guys were amazing.
Moss? He had all the tools, but he publicly admitted he took plays off. Most would say he took games and years off. He could have been great but then he got high. To me, Percy is a better comparison to Moss. Guys who never achieved what they could have.
