I guess I'm in the minority here based on the thread, but even with full effort throughout his career I think Moss is 2nd to Rice. Let's not forget that Moss put together some absolutely monstrous seasons in Minnesota and New England and he STILL ranks a full 8,000 yards, 44 touchdowns, 600 receptions, and 3 Superbowl Rings behind Rice. Those aren't gaps, they're chasms. Moss would have needed 8 more seasons of work to even approach those numbers, so I don't think it's just a matter of effort. Rice was just hands down the best ever.
