I kept thinking it had to do with some kind of code they'd use in a no huddle offense, like if a player was supposed to do this or that maneuver they'd tag their name with Dog. So if Tom's calling the shots and AP Mike, Pat and Slaw were in the play he'd yell out: "MikeDog, SlawDog, HUT!"
The bit about his coach accepting the "I'm failing math" excuse was the best tag on that story. So hillarious.
Cheers to SlawDude!!
