Takedowns and Takedown Defense
This is where Kelvin Gastelum has a chance to make things interesting.
He has a wrestling background and isn't the type to sit in an opponent's guard and eat strikes like Dylan Andrews did briefly in the semifinals.
As good as Uriah Hall looked off his back, his takedown defense was not tested enough throughout The Ultimate Fighter 17. If Gastelum can turn this into a wrestling match, he could pull off his biggest upset win yet.
Control and Escapability
Hall was active when forced to fight off his back, but his ability to escape or reverse positions with grappling was not really all that impressive. The deadly striker had a chance to at least sweep Andrews with a kimura, but he never seemed to fully commit to the submission attempt.
That said, Gastelum was far from flawless on the ground on the reality series.
Gastelum was not put in any bad spots in his fight against Josh Samman, but his bout with Bubba McDaniel was sloppy. In that matchup, Gastelum was reversed and had his back taken multiple times before finally locking up a submission.
Submissions and Submission Defense
Though Gastelum has a couple of submission wins on the show, he's much more even with Hall in the jiu-jitsu department than the reality series would lead one to believe.
As we saw in his bout with Andrews, Hall does know how to work submissions off his back, and that could prove important against a wrestler like Gastelum. Although Hall didn't force a tap from Andrews, he has submitted a previous opponent with a heel hook while competing under the Ring of Combat banner.
