Well, if we are going just by tournament work, it's an easy argument to make that he's been one of the weaker guys to have made it to even round 2. He's yet to really have a blow away good match, and the "he hasn't faced good opponents" argument doesn't hold, cause Drew Gulak as pretty damned great. He's had the worst tournament out of anyone in the final 4, and if it weren't for Dar, the same would probably be said of anyone in the final 8.
It also hasn't helped that Jack Gallagher came across as a 20 times better version of someone working a very similar style. Also, his strikes look like shit, and he's an awful seller.
