Just looks like Poling goofing off with a happy Coach. I wouldn't read any more into it than that.
That's how I saw it too. Just a spontaneous and well-earned moment of joy. What happened last night was great. Ohio didn't have the great season we all hoped for, but we certainly turned it into a good one. A bowl win would be the whipped icing (because buttercream is stupid and disgusting) on the cake.
