I was going to join until the re-buying entered the discussion. This should be single elimination winner take all.
1 person talked about a buy in, I don't see a lot of support for that
but I think it looks as if we may be going with a double elimination. We pay the last undefeated team 1k, and that team will still be favored to win it all. The overall winner gets the balance
for $ 500 it gives the contest a little more juice, and the pool is so small the contest may be over in 8 weeks with single elimination.
