From the results I read, Fedor never seemed interested in going after a finish in the fight, he was just content to stay ahead.
I trust you hate him as much as GSP now?
The results mislead you a bit then. It was because Fedor was trying to finish why he came off like he was playing it safe, if that makes any sense. You see, as good as Monson is on the ground, he's not catching someone like Fedor off his back because of his size. However, he'll do enough to survive, and Fedor knew this. On the feet, though, I don't think Fedor thought Monson had it in him to do enough to survive, so Fedor kept the fight there. And trust me, every upper-cut and overhand right Fedor threw was with the intent of knocking Monson's head off.
It was nice to see Fedor show a little patience, though. If he had that patience in the Werdum and Hendo fights, there's no doubt those would have gone much differently than they did.
