Fedor's fight with Brett Rogers, he struggled. Of course he was giving up some 40 pounds of weight, but he always was the smalller guy and it never bothered him in the past. He looked slower, weaker and unmotivated. He still dominated every second of the fight and KOd the guy but this was the fight that was an eye opener for us Fedor fans, that he is beginning to slow down and becoming reckless. Fedor was fighting for 9 years and was undefeated. He would go on a bad losing streak from this point, many believe he should have retired undefeated. GSP retired at the young age of 32. He did it after he had a tough fight with Hendricks which many believe he lost. He was dominated in that fight in every aspect of the game. He slowed down too and with usada looming around, it was time to call it quits. Jones will be 33 this years and he too seems to be slowing down, allowing the rest of the pack to catch up with him. He looks very beatable now, he was arguably beaten in his last two fights. Should he retire undefeated? Goats retire or start to lose steam at young age! 32/33 is that age. except for Anderson who ruled the world till 38.
