What cornerbacks make Randy dissapear? The only time he dissapears is when shots aren't taken at him. If it was as simple as just jamming him at the line then that's what teams would do and he wouldn't be dropping 20+ TD seasons on the league. I remember once when he was with the Vikings, the GB Packers actually lined two corners up right over him and had them attack him like he was a runner on punt coverage. Is he as big and strong as TO? No, but neither was Jerry Rice. It's not all about being the strongest. Strength and being able to fight off a NFL DB's jam isn't the gold standard in which all around athletic ability is judged.
I don't know what leads you to believe that he doesn't have blazing out of the gate speed. Deion Sanders was on record with the fastest 10yd takeoff in NFL history, and Bobby Bowden says that when Randy got to FSU, he ran a faster 40 than Deion did. 40yds is a pretty short distance that gives a good idea of somone's out of the gate speed, and when a guy runs a faster 40 than someone who has the fastest 10yd takeoff in NFL history, I think it's safe to say that his out of the gate speed is decent. The 55m is also an event he won at the southern track championships. Shortest event in track that is based completely on out of the blocks speed. Here is a video with Hall, who was timed in the sub 4.2's talking about Randy's speed (pay attention to the reference he makes concerning TO, who do think he feels is tougher to cover?), along with some highlights that best display his speed. Two plays that stand out concerning his acceleration are the screen pass against the Titans. Watch how quickly he pulls away from Samari Roll (#21) and the screen pass vs the Saints. #23 is Kevin Mathis, who was listed in Sporting News a few years earlier as the fastest man in the NFL with a 4.19 time... watch how Moss out accelerates, and then just pulls away from him and the rest of the field.

The notion that Moss's speed is lacking in any department is beyond ridiculous. When a guy who coached Carl Lewis for the Olympics says that Moss is the best runner he's ever seen, I think I'm going to go with his opinion and what my own eyes see on the matter. Another thing about Moss that's just sick is that in an interview I read a few years ago, he claimed that he's never really ran just all out as fast as he possibly could in a game because it's never been necessary.
And speaking of Deion Sanders, someone else mentioned him here as a canidate, and he definitely deserves it. However, he was a guy who was known for not being a big fan of contact, and wasn't a big muscle bound power player. Does that really matter when discussing his ability as a great athlete? Bobby Bowden also says that Deion was the greatest athlete he ever saw, until Randy showed up. Is that meaningless because their arms aren't as big as TO's?
And if you notice, my post didn't name Moss just because of his accomplishments as a receiver. That alone wouldn't make him worthy of the title. I see him as one of the greatest athletes because as great as he is as a receiver, it's said that football wasn't even his best sport, that baseball was! So think about what type of baseball player he could've been? Then there's the fact that he could be in the NBA, and that a guy who coached the man considered by many to be one of the greatest sprinters and olympians of all time says that Randy is better, and you are left discusssing a guy who is just flat out ridiculous at a host of different sports.
If you have another canidate, then please feel free to post them up with some reasoning. But calling my observation retarded while claiming things that clearly aren't supported by the evidence doesn't make for a very productive discussion on the topic.
