Without a doubt it's DJ.
He uses everything routinely, and his best work is in transition.
His clinch game is disgusting and very active. It's one of the best in MMA.
His footwork is great and his scrambles are world class.
Physically, his conditioning, preparation, speed, ect. are unquestioned.
Mentally, his ability read, react and adapt tactics is out standing.
He has fantastic coaching.
Oh, and he's very very good at wrestling, grappling and striking.
He's beat up guys with nasty ground and pound, he passes guard very well, he's shredded guys with his clinch, has submissions from mutliple positions(including the air) and lights guys up with with kicks, punches, knees and elbows.
It's DJ.
