Stipe is 38 and recently had eye surgery to fix eye poke damage. IMO he needs to have a plan for just one more or maybe two more fights and then retire. Father Time is undefeated and untied and this is MMA not tennis. When you lose you in MMA you can receive a massive physical beating vs. an embarrassing 6-0 6-0 score with perhaps slight blisters on your feet and dominant hand. In a competitive fight, even the winner can absorb a fair amount of damage. Broken nose, broken jaw, broken orbital bones, concussions, etc. are not uncommon...Tony Ferguson (36) recently hit the end of his high mileage odometer and his last two fights have not been pretty to watch. You can be great and then boom...Father Time shows up...the difference in speed, timing, reactions is the difference between being elite at the highest level and winning regularly vs. racking up losses and absorbing beatings. Throw in loss of confidence on top in a sport that requires your mind to be strong and positive.
MMA fighters should definitely keep an eye on when best to get out...it's not like football where the coach or the GM will cut you because they want to win games and there are so many young players coming up through the system...If the UFC or other promotion can book a fight with a big name older fighter and generate revenue, it doesn't matter to them if the big name older fighter wins or loses like an NFL team that has to maintain a good record in order to make the playoffs. Chuck Liddell helped make the UFC, but they let him absorb three beat downs by KO at the end of his UFC run at age 39 - 40. I thought the Rashad Evans loss should have been the end when he was laid out stiff for a long-time, but the UFC let him go out twice more vs. Shogun and Franklin. The Franklin fight was entertaining as both fighters were old and winging heavy stuff, missing a fair amount, off balance at times and then Franklin put Liddell's lights out with a counter right hook to the face. Two years later Franklin (38) would get face planted KO'd in R1 by Cung Le and he retired afterwards. Franklin was doing well against Cung Le until he wasn't. Liddell was doing well against Evans and Franklin until he wasn't. I don't want to see Stipe in the cage for a 25 minute bout and find out he is clearly spent vs. someone like a Ngannou who is probably the hardest hitting MMA fighter I've seen.
