That's a helluva lot of people to gather to meet and talk and try to get things done.
Someone (Geno?) should take the approach Red Auerbach did in the old NBA days. Every year they held a big meeting of all the GM's to discuss rules changes, policies, etc. In Red's book ("Let Me Tell You a Story") he explains how all his motions got passed. He would never bring any issue up until about 4:30 p.m., when conferees were tired, talked out, and THIRSTY. Knowing that it was easier for them to go along with Red (and get to the bar!) than argue, he always got little advice and lots of consent.
