thing was staged.
supposed to cause a lil drama and wandy took it further than sonnen was anticipating.. you can hear sonnen say something under his breath when he took him down.
if wand wanted to connect, he would've.. as many bareknuckle fights as he's had he wouldn't have missed in the first place, secondly, he would've came in with a hook or a str8 right and would've went to the clinch instead of pulling guard so easily.... esp with sonnen wearing sandals on concrete.
sounded like wands elbows to sonnen were actually landing though, but that could've been added later in post-production... not like it was live.
