rewatching nick and condit, Nick was throwing alot of body shots which I don't see alot from nate. I think with his pressure style which makes his opponents gas, those body shots would be pretty useful. great post right?
Nick gets inside a lot more and in doing so, is able to easily work the body with combos. Nate stays on the outside more and uses his height and reach. Nate did land some nice knees in the clinch though. 
Do you know Nick and Nate are not the same person? 
I remember Nate throwing some body shots, including punching the chest.
He also threw a bunch of good knees.
