3 guys who need to retire right now.
They have all had great careers and have been the best, or 2nd best, at some point. They haven't started racking up losses yet but their recent performances demonstrate that they will if they keep fighting.
Please. All of you. Go out on a high note. If you stop now you'll be remembered as legends who were still comptetive when you quit. People will claim that you could have still gotten the title back (they're wrong but at least they can make that claim with a straight face now, they won't be able to a year from now).
The problem all these guys have is their marquee name and reputation means they can't fight anyone but top contenders (rare gifts like Coleman and Perosh aside) but they can't beat any of those top contenders.
Big Nog is the one people are still going to claim is the most relevant but out of the top UFC HW's who the hell is he going to beat? Lesnar, Carwin, Cain, JDS, Mir; I just can't imagine him beating any of those guys. Don't spend the twilight portion of your career as a gatekeeper or even worse, some kind of Shamrock embarassment.
They won't quit, I know that. They never do, not in MMA or any sport. Wayne Gretzky quit while he was still decent. Rocky Marciano. I can't even think of any others. Bobby Orr but he was forced into by injury.
I just don't want to see these guys start racking up losses and it is going to happen if they keep fighting.
