The way we could do that is to either randomly assign teams to everyone who participates, or each person could choose a team that they prefer. I know who most of the people prefer, except for some of the silent readers, and there are only a few overlaps, so maybe we could decide those by random choice. For example, there are at least two Red Sox fans I know, so they could each choose a second team that has not been picked yet, and the one who does not get chosen to get the Red Sox gets their other choice.
Group Break Explanation
For those who may be interested, what I will be doing for a Group Break is buying a case of some product, whatever is the general consensus, but something with a good deal of "hits" such as autographs or relics. The idea behind it is that I can't afford to buy a case of something, but if 30 of us chip in $20 apiece, then we could get a decent case of something and share in the results. For something like UD Elements that has 48 "hits," the chances are that everyone would get at least one. If you want to see how a "pro" does it, check out Jawdy's Basement. There is a recap the Upper Deck Heroes case break he did, and it is pretty impressive.
