You can't thaw butts and brisket in a day. If you buy 5 to 7 days ahead of a contest, it should be OK just refrigerated.
There is a wholesaler about a mile from where I live. Based on what I've read, it would be acceptable to buy what I need about 5-7 days early, freeze it, and thaw it the day before a competition.
