I recall someone posted a thread here recently asking to name a fighter that would benefit from one particular strength to be unstoppable.
Arlovski WITH a granite chin would be my choice. His striking has always been SO deadly, the guy is so quick for a HW.
He would be a great addition to the UFC if only he posessed the ability to take a big shot. You're fighting at HW. Anybody in that division has KO power simply because of their size.
