LOL... they are coaches.... Do what you do best, they only want the beer and BS.
That being said, were it me, it would be nekkid chicken, spare ribs and sausage.
Don't worry about party favors or finger foods. No women involved, no need for rabbit food.
Meat. potatoes, and beans. Maybe swap the taters for some of the smoker mac & cheese.
Cold beer, smoked or grilled chicken, few slabs of ribs.
Or
You can always cook a butt ahead and reheat for that day. Butts are great reheated, actually better reheated than hot. You can get some of that famous JJ's finishing sauce on them. Totally off the chart!
Whatever it is, just make sure the beer's cold and remember the first liar never stands a chance.... LOL
