Shoot your shot. Gimme your best guess as to how many teams go undefeated to a Natty until the playoff expands. We've only had two so far in the seven years weve had the playoff (and a full season) but with 3 teams going 13-0 in 2019 it was virtually guaranteed. Bonus points if you guess the teams and years of the ones that go 15-0. Tiebreakers are when do you think playoff will expand and when you think that announcement is made (in that order)
