Erick Paulson is working with Brock. I have known paulson for 15 years, he is a top mma instructor and BJJ instructor with phenomenal leg locks and submissions.
As for Mark Colmon, Mark Laimon works with him on his submission skills. Mark is a top notch instructor, but Colmon doesn't really like to do what he is told or likes doing drills.
My pick is Brock, but he will get eaten up at a later time by , Gonzaga, Nogara and a few others. If he loses 2 in a row, he will be fighting for WEC..
