Meh i think both of their striking games suck. Which may make for a good fight.
Gomi has basically 1 strike. He is crouched over like a hunchback and his power hand usually comes up a foot short. Sure he has Ko power and a chin, but he isn't a good striker. There is little shame in it at this point, but this was obviously when he fought Nate Diaz. On the ground Nate schooled him and everyone realized he would. So that left Gomi with 1 chance, striking. And Nate made him look like a rookie in that department. Vs. any disciplined, solid technical striker, Gomi will look like crap standing these days.
Sanchez has never been a good striker. His volume and aggression do him well vs. other average to below average strikers. But he usually gets beat up pretty bad on the feet. His strikes have little rhyme or reason, it is just a cluster fock of nothing.
