He's all about toughness and competing. Watching the defense get big hits, defense passes and stuff the run you can see that twinkle in his eye. He wasn't jumping around and screaming but that smile on his face was just like "Yeah I'm liking this" .
Even when McFadden drew that personal foul after the play was over, Tomlin just smiled at him. He didn't start yelling at him, he just gave him a pat on the rear and a smile to someone else beside him.
Watching Ben, Charlie, and BSP air it out in the first quarter he was just taking it all in stride but I got the impression overall that he liked what he saw. There's still a long way to go and we had a lot of mistakes but for a first presason game it appears that Tomlin is indeed well in control of this team and genuinely likes how his guys are out there competing and mixing it up.
