I can't remember seeing Cormier use a power double like Lesnar.
Cormier usually seems to just want to get deep on a single, pick you up and throw you down. Lesnar usually just shoots a power double on you and pulls you to the mat, doesn't try to pick you up in the air which IMO is more difficult than your traditional style power double or whatever.
Both Lesnar & Cormier are very different styles of wrestling in terms of their way of taking their opponent down.
Brock usually just tries to time his power double or he'll just overpower you with that insane drive. Cormier usually puts you against the fence and goes in on a single or clasps behind your back and wants to literally throw you like a rag doll. Their styles are very, very different. Personally, I think Lesnar's style of TD's has proven to be more effective in MMA over the years. The power double or single, IMO, is better than slamming your opponent. Odds are you're going to land a double or single before you get a slam like Cormier.
I know some people will disagree with that, but look at guys like GSP. He didn't want to slam you down, he used the power double and it gave him great results and he's arguably the best wrestler MMA has ever had because of it. There's more wrestlers in MMA that rely on doubles or singles instead of slams because slams are harder to get most of the time and you often use more energy because it's basically you just overpowering your opponent sometimes, because sometimes, you don't just use leverage, sometimes you literally do have to overpower your opponent to get those kinds of slams.
I have no idea how Lesnar/Jones would go. I wouldn't be surprised if Brock would take Jones down quicker/easier than Cormier did though, honestly. Brock's power double was fucking insane in terms of speed & power, also the timing was great, too.
If Jones can stop the TD's then it's going to be Jones all day. If Brock is able to take him down, I'm not sure what happens. I don't know if Brock would be able to hold him there but it wouldn't surprise me at all if he could.
I'm thinking some people will mention when Jones got back to his feet really quick after Cormier threw him down but Jones didn't land on his back, he landed on his knees, so it was much, much easier to stand up immediately. Brock goes for TD's that will always end up with his opponent on their back, not their knees. That's a big difference.
Cormier is the much better, more skilled fighter though, clearly. But Brock was no joke and his wrestling was absolutely fucking insane. The speed, the drive, the timing, man, that power double from Brock was unbelievable and I wouldn't be surprised at all if he was able to take Jones down and control him. Honestly, I wouldn't be surprised.
Brock gets a lot of hate but he really was a beast. He wasn't the greatest fighter around but for him to come in with no MMA experience/much time of training and all and to win a title in the UFC, that's impressive.
If only Brock got into MMA when he was in his early to mid 20's, imagine how great he could've been.
