Revis is well respected within the industry and league that I think his chances if he would retire right now would be good. (Better than 50-50) I agree with the statement that about 2-3 more years of solid work should solidify it though. Keep in mind this was only his 8th year in the league and he lost that entire year with the ACL.
The fact that his career has been defined as a man-to-man specialist in a completely offensive pass happy league, and he completely shuts down players will be his legacy.
To answer the specifics, I just looked at Wikipedia. He is a 6 time Pro Bowler, and a 4 time First Team All Pro. Now, people might want to say that he only has 23 interceptions which puts over 250 people ahead of him. I don't know where to look for the advanced stats, but most games Revis has about 2 balls thrown his way and that is because QB's know they can't go there...
