Mullin should def go see that coach at CTK, shake his hand, tell him he'll be around often.
But then, as he's leaving, Mullin should grab him by the ear, throw him to the ground, and tell him that I'd he ever posts garbage about the him or the program again, he's going to rip off his ears and shove them up his ass.
Then, Mullin should help him up, dust him off, and take a photo with him. Big smiles in that picture, too.
