Tony's best days are behind him imo. I felt like he got hit way too much in previous fights but that Gaethje fight was the last straw. That type of damage is lasting and with the way Tony fights, I don't see him surviving too many more fights.
Sadly I feel this way too. I remember after BJ Penn lost to Nick Diaz, I remember thinking that was the kind of fight that BJ probably wouldn't rally from. And there were obviously other factors there too, so it's not a perfect analogy. BJ was dealing with an evolving fight game that was passing him by, and fighting guys outside of his natural weight, and also an unhealthy personal life.
But there are just certain fights where I get a bad feeling that the fighter won't ever be quite the same, and I definitely have that feeling with Tony. I actually had it before the Justin fight. I thought Tony earned the right to sit and wait for Khabib. But him agreeing is kind of a big reason why I love Tony. Same here. I think he's kind of dumb for agreeing to a fight this weekend with very little upside to it, but I respect Tony's warrior mentality.
This is such a brutal sport if you're truly a fan of anyone. On a long enough timeline you'll always see your favorite fighter get beat the fukk up. GSP is pretty much the only legend I can think of that made it out of the game relatively unscathed on their way out the door. Edit: And I actually wouldn't say that if he hadn't come back to fight Bisping, because he got tagged up in the Hendricks fight.
