Sonnen is a different type of wrestling then GSP. GSP uses his striking to set up his quick singles. Chael Sonnen just shoots power doubles all day and even if you stop 1 or 2 he will take you down with the third. Power Doubles are actually pretty easy to stop when you know they are coming so the fact that he gets as many people down as he does is nothing short of amazing.
