Once we get to game 121, we can trade 2 seasons in advance, however the trades are done in the forum and the players don't switch teams until the next season. Wins floor: 50-45-40-35 (1st round only)

It's time to crank up my favorite variation of the Birthday game. When you sign up I'll generate 25 random birthday days at random.org. . OK so far, and you have to use each birthday once. The new pivot is that if you're stuck on one date with no good roster choices you can designate it as your one death date and choose a player that died on that day. Using baseball reference you can find these lists at : https://www.baseball-reference.com/friv/birthdays.cgi & https://www.baseball-reference.com
