Who What Now?

I'm still trying to figure out this "nugget" of newsworthy information:

Tomlin making friends: Just after Monday's night's 38-7 domination of the Ravens, the new, emotional leader of the 6-2 Steelers waited in the tunnel to high five and hug every player as they came in. Who was it? Rookie head coach Mike Tomlin. Unlike former head coach Bill Cowher, the 35-year-old Tomlin generally isn't a rah-rah guy. Also unlike Cowher, Tomlin isn't a yeller, which players appreciate. Ben Roethlisberger told me Tomlin "has brought fun back." -- Bob Holtzman

So Tomlin high fives and hugs every player after a game and he's NOT rah rah? What is the definition of rah rah? But I guess he didn't yell while he was doing it, so that's okay. And coaches who don't yell, and aren't rah rah...how can they be fun? Maybe he throws great parties?
