Liddell vs. Nogueira ?

Well, in a recent post, Liddell said he would fight Nogueira if given the opportunity but he first wants his light heavyweight title back. I thought it was interesting that he would be willing to step up into the heavyweight class. It makes me wonder what weight he normally stays at. He's a big boy, but I wonder if bigger guys would take him down? Who knows...but in any case I thought it was interesting.
