The way they both have changed, Machida KO easily. Shogun has gone down hill while machida hasnt gone down hill and maybe stayed the same. he is still very dangerous for anyone, and can close the distance fast. Shogun didnt beat up machida for 5 rounds like GSP/AS or Bendo (recently) dominates people. Shogun studied him and fought him for 5 rounds and got his timing right. He caught Machida coming in, it happens to the best, in the sport of MMA anyone can get caught with the little gloves we have.
Shogun is just not the same Shogun of old. I really do think Machida will win a 3rd fight. The same way I think Machida will beat Hendo. Even though Hendo and Machida are my 2 top active fighters. Machida to me is more dangerous. As long as Machida can keep the distance with his karate, he will tire out Hendo or catch him coming in. However, having said that, he needs to be VERY careful in the clinch, and with Hendo's huge right hand. The H Bomb can land on ANYONE, thats the one thing that scares me about this fight.
Shogun should retire, just like forrest, they just cant cut it anymore
