Outside of Head Kicks Gonzaga hasn't shown much as in the stand up department. I mean his head kicks are nasty but he hasn't shown techinical stand up skills and outside of the head kicks I don't see a major difference in Gonzaga and Werdum standing.
He has also shown KO power with his hands. His debut may have been boring as shit, but he sure ended it well. He also stunned Couture with a few punches. If Werdum wants to stand and trade, I give Gonzaga the KO win.
