If you dislike or downright hate WWE, don't click on this so that way, you won't feel inclined to comment that is is an MMA site. Now I watched WWE back in the good old days and I still occasionally take a look here or there and I always come to conclusions about whether or not these guys couldve made it in MMA
Heres the one I really would have liked to have seen what he could do.
Jack Hager better known as Jack Swagger was recruited by the University of Oklahoma and won All-American Honors in 2006. He is billed at 6'7 and 260 pounds but I can't say how accurate that is. If that's true, then he would be one of the bigger UFC heavyweight fighters. Watching him on screen, he is very very athletic, seems to have a good motor for in ring performances, and has very long arms as well. I would have loved to have seen him come to MMA to see how he would have done.
Another guy would be Kofi Nahaje Sarkodie-Mensah aka Kofi Kingston. Billed at 6' and 212 pounds, he could probably cut to be one of the larger middleweight fighters. Although he has no actual fighting credentials I could find, I love his ridiculous athleticism and flexibility and feel like had he been trained, would have made for an exciting standup fighter.
The next guy would have to be John Randall Hennigan aka John Morrison. Also an incredible athletic talent who has great speed, agility, flexibility, stamina and is better looking then Jake Sheilds to boot. He would have made for an exciting Bjj fighter since he has such flexibility and control of his body.
The next guy was a very accomplished amateur wrestler. Shelton James Benjamin was a two time South-Carolina high school state wrestling champion with a record of 122-10. At the University of Minnesota, he was a two time All-American and placed 6th in the Big-10 championship. In 2000, he decided to try professional wrestling instead of the Olympic trials. Imagine if he had chosen MMA instead of pro wrestling. He was clearly an amazing athletic talent with great wrestling. I think he would have been able to really make waves in MMA . He is the guy I really wanted to see in MMA more then any of the other guys.
You suck! You suck! You suck! Kurt Angle, a WWE icon who was terribly underutilized and should have become one of the greats. However if he came into MMA instead, he would have been the most decorated wrestler to ever fight in the UFC. Three time division one all American, two time national champion, took gold at the 1995 world championships and won the gold medal at the 1996 Olympics despite his severe neck injuries which occurred during the trials. Had he come to MMA before WWE, he may have had the potential to be one of the greatest fighters ever.
I would like to add more but I would like to hear opinions from whoever has any ideas on guys who could have made great MMA fighters.
Honorable mentions: Undertaker (really fast hands for such a big man), Randy Orton (athleticism, size and range), CM Punk and Daniel Bryan (both train in actual martial arts i believe).
Anyone else you guys want to add?
