I know it's a million to one odds but we actually had two people tie for first in our league. I'm the commissioner, what is the tiebreaker? Is it most number of weekly season wins? That you have set by default as overall season winner.
if it's a money league, you split the pot if you had no tiebreaker in place.
you can't invent a winner after the fact if you didn't have a rule in place.
