The dude has accomplished quite a bit especially with the win in 205....u can call it lucky if u want, but nonetheless it was devastating. Im a huge fan of Silva and I would think he has quite a bit of fight left in him...enuff where he could still leave and not be close to Randy's age, after a few more fights. His last fight with Cote showed me a side of him i have never seen before....he usually has more sportsmanship than that, but hey he is human. No one is perfect, we all make mistakes. If he feels its his time to go he probably wants to go out on top...i would love to see him stay personally but hey im not the one in there defending a belt against bloodthirsty fighters...LOL...
