Josk Koscheck has really seemed to step it up a notch, most noteably in his recent win over Jonathan Goulet. After this, I hope he starts getting some tougher opponents that will test him a bit. Goulet seemed outmatched the whole time, but so far the new Koscheck has impressed me.
Diego Sanchez has turned into one of my favorite fighters to watch, just based on his last two performances only. I think he's really going to work to improve his stand-up, and we'll see an even better Diego throughout 2007.
Georges St. Pierre has obviously won me over the most. He's my favorite fighter, he's an incredible athlete and he's gonna look good as the Welterweight Champion.
