They are not even remotely similar.
First of all Ellenberger wasn't even a high level wrestler in college.
He's a hyper experienced sprawl and brawler with dynamite punching power the dude nearly flattened Condit on his feet for God's sake.
Hendricks has unique skills with the single collar tie clinch and in fighting as well as a huge left hand as a backup to complement his wrestling skills.
And Chad Mendes just sucks. He's just an athletic negative point fighter.
None of them are similar to the other.
