I'll likely do grilled sirloin tips but just for myself. May or may not be BBQ. I don't do 'parties' anymore as I have become pretty much a hermit.
Last time I did a football party thing was several years ago on Thanksgiving. Invited a couple of guys in my apartments that I thought friends over for dinner and football. I did the full thing with turkey and all the sides. After eating bunches they both said they had to leave to watch games with friends. One guy actually knocked on my door later wanting "his share" of the pumpkin pie. Keep in mind that neither supplied or even offered to bring anything. I have not done such a dinner since.
