There is a HUGE difference between Anabolistar Testostereem and the fighter the dutch is right now.
Just look at the fights after and before the testosterone issue. Brock was #3 #4 HW ??? And overeem almost is out the TOP 10
That isn't roids as much as Reem not keeping his hands up and his chin tucked. Look at the losses...All came after he was putting a thrashing on guys and gassed.
When he fought Brock, he actually took precautions and kept his hands mid range. Not too high or low, he wanted to be ready for punches or the takedown. He fought intelligently. Against Brown and BigFoot....AND Rothwell, he really just seemed to either not take them seriously, or was overconfident to hell. Keeping his hands down, and having no respect for other heavyweights' KO power.
Bigfoot- He was doing what he wanted in the first, after that he began to slow down and gas. Bigfoot took advantage in the later part of the fight, and it still took an immense amount of powershots to put him down.
Brown- Brown was getting the literal bricks beaten off him, downright looking like a child who pissed off the wrong daddy. Then he weathered the storm and spammed a front kick into a not too intelligent Overeem. He literally had his hands down and his chin out infront of him.lol
Rothwell- I still have no clue why he did not take Rothwell seriously, the guy is tough as nails and is a huge/powerful heavyweight. He straight up showed no respect for Rothwell and payed dearly.
You see where I'm going with this? He took 1 guy almost too seriously and destroyed him pretty badly. That guy was Lesnar. He gave Lesnar absolutely no opening to impose his gameplan...Not once. That is the key difference.
Now I'm not saying he would win the rematches against those men, he could very well lose them again, but to say it was all based on roids is pretty idiotic given the evidence in his approach in all those fights point to him just thinking his shit didn't stink.
