Tim Kennedy: army bad-ass or grinning goofball?

I didn’t have a lot of interest in tonight’s (Friday’s) Strikeforce: Challengers card to begin with but seeing headliners Zak Cummings and Tim Kennedy grinning at each other like a couple of college goofballs like one of them just farted during the weigh-ins has me even less enthused. Kennedy is a green beret and a sniper and all-around Army bad-ass. Where’s the animosity or intensity or thousand-yard stare, the one that says “I’ve seen some shit”?
