Brock Lesnar is a tank, sadly his armor had been hampered by a bulleting illness. Diverticulitis. I knew he would loose to Overeem cause Brock's liver has been heavily affected by the disease, and Overeem Kicked it.
Brock Lesnar can't be undefeated cause he lost 3 fights already, but he can be undisputed if he works on his skill and defense, I agree on that. Junior Dos Santos is a monster without a doubt, but he is not keeping the title forever, despite my prediction of Dos Santos retaining his title against Overeem.
Brock will come back, and eventually, if he recovers long enough, he will be unstoppable, not even Cain Velasquez, or Overeem, or Mir will be able to stop this man by then.

I like watching Brock Lesnar fight. But I think he should work on his stand-up offence & defence and not focus on his wrestling as much. He's got his takedowns & ground game pretty much down from what i've seen, if he was that good at his stand-up too, he'd be one of the most successful fighters in the UFC in my opinion.

Brock Lesnar is way overrated. All he does is lay on people. He shouldnt even be in the mix for a title shot. Junior dos Santos will destroy Brock.

he isn't skilled at much accept for wrestling but his power will always be a test for any fighter

Compared to other MMA fighters Lesnar has no skill. Before his illness he also had no class, but I must admit I was getting used to him, seeing as he was acting less douchey.

If he doesn't just count on his enormous size advantage, and actually gets some skills then he'll be unstoppable.

this guy has to have 10 for chin now, he just endured what no one ever has lol
and maybe give him some more props for submissions lol

carwin never landed a flush shot on the chin. watch the fight again buddy ;)
carwin nicked lesnar with a left uppercut to the nose. than just landed shots on lesnars, arms, and head, never his chin

Brock is a beast hands down. Shane Carwin is also a beast but Carwin likes to stand up and trade punches witch we have seen isnt good for him he gets rocked to easy. Now brock on the other hand he can stand up and take hits we've seen this also and his stand up is great but is wreastling is AWSOME!! So even if Carwin can keep it standing up he still dont have a very good chance of winning. Thats to say if he can keep it standing up and that a freaking GAINT if. Soo im giveing it to Brock

i get that he is strong, but i hate every thing about Brock Lesnar. Shane better destroy him. lets hope its the same ref from the carwin mir fight. I seriously thought mir was going to die.
