Ok and Jon Jones was only taken down by two people, Alexander Gustaffson and Daniel Cormier. Gus had the reach and Cormier had the technical greco roman aspect, what would St Pierre do?

I agree - I don't think you can say otherwise if you know fighting.

Better wrestlers? How well do you know St.-Pierre? He has outwrestled all the best fighters who were nationally ranked wrestlers in their college days.

GSP is my favorite UFC fighter of all time, and given my choice I'd want him to win. I came too early to the game for MMA, but I was a collegiate wrestler, a boxer, a full contact kick-boxer, a judo player, and I've done a lot of aikido and hapkido, so I know something about fighting. Your algorithm is useless! Jon Jones would absolutely annihilate GSP. This is a silly discussion. At the end of the day speed is the issue. George is fast, but Jones is just as fast. When the bigger man with the superior bone structure/anatomy (for instance: killer elbows and the right bodily proportions to use them like no one else in the game) is as fast as the smaller man then his size does matter.

I think jon jones would really win

Regardless of weight Jon Jones has a lot more control over the wrestling aspect. This site doesn't really take into account that styles make fights.

No doubt about it. If anything Jon Jones faced better wrestlers like Chael Sonnen, Rashad Evens and Daniel Cormier. I remember when he fought rampage and you may be able to watch it in the highlights. Jon Jones goes for a high spinning back kick leaving him venerable to be taken down and as Rampage attempts to go for the takedown Jon Jones does the most inhuman motion and does the fastest sprawl I have ever seen.

You are an idiot, this has nothing to do with race you fool. If you bothered to look at all the match ups on here you would see it's a cold algorithm that works it all out based on statistics. One thing though is it seems that weight is not included in this algorithm. My guess is it's only meant for fights in the same weight class and they didn't consider stupid match ups like this. It has nothing to do with race though you fool, this site also claims Jon Jones beats Cain! Get it? So stop cherry picking and you will find tons of stupid ones where it says the black guy will win when he is smaller also. Race isn't part of the algorithm. It has Demetrious beating Stipe Miocic also. http://cagerank.com/G0cl.G0eI/Demetrious-Johnson-vs-Stipe-Miocic So stop being a fool looking for racism where it clearly isn't. Use your brain more, all that is at play on this site is an algorithm that doesn't take into account the weight of the fighters. Get over it

I feel like the calculator/algorithm or whatever it is, should take some account of weight , off season weight, strength (maybe based on some {weight class, lifting numbers -calculated speed of striking over and over on videos-, strength coach} equation). And maybe the ability to take on bigger opponents (minowaman, manhoef would benefit from that) based on history of fights ? Talking about history, controversial decisions (gsp hendricks...) could have some impact. Also not sure if I saw winning streaks taken into consideration here. And what about southpaw/orthodox and people who are good about both? (wouldn't apply in weidman-silva case, but may be interesting). In the end I think the skills > size (within some interval of athleticism-endurance-strength-size, rousey fedor, wanderlei aldo would be no match), approach is not flawed. IMO Jones would beat Lesnar, for example.

Jones would decimate GSP.

Yeah, the favoritism due to the Caucasians users on this site isn't blatantly obvious here ... there's no way in Hell GSP is doing anything to Bones ... ever....

You can't make predictions based on statistics alone. Especially when the context is completely wrong. For a starter it is almost 40 lbs weight difference between GSP and JJ. JJ would use GSP as a punching bag ...
