Hmmm, was much more competitive than "complete domination." Hioki dominated 3 and 5 but iirc 1, 2, 4 were competitive. Hioki ended both 4 and 5 with locked subs, wonder if he would have popped Sandros elbow if he had a bit more time at the end of 5.
Anyhow, seems Hioki was still able to be taken down a couple times by good shots by Sandro which could be a problem for him in the UFC though he has an excellent guard, how much with the fence play in? It was also due to the match being established as a boxing affair first though, the tds imo.
Still, Hioki has many tools both standing and on the ground.
