Patrick Mahomes is the first Big XII quarterback to win a playoff game, since the Big XII became a thing in 1996.
That's insane that it took 22 years for a QB from that pass happy conference to have a single postseason win.
For comparison, during that same time: the Pac 12 has had 14 QBs combine for 63 wins; the Big Ten has had 5 QBs combine for 48 wins; the SEC has had 7 combine for 30; the ACC has had 5 combine for 8. Even Conference USA, the MAC, the Mountain West; and the FCS CAA and Big West have had multiple QBs win postseason games.
