Not to take away from the topic at hand, but Arlovski wasn't "beating Fedor pretty bad" in the striking, he did little to no damage and if you look at the slow mostion he misses a lot of his strikes. In fact, the only thing that hit him solid was the push kick right before he got knocked out.
With that said, Fedor is not the best striker in the world.
