Did that change with the change of rules when the CCG was added?2nd place seems to be the precedent.
2015: Oklahoma (#4) is the conference champion, and goes to the CFP semifinal. TCU (#11) is the next-highest ranked Big 12 team, but doesn't get in. Oklahoma State (#16) goes to the Sugar Bowl. OSU and TCU tied for 2nd in the Big 12 at 7-2, but OSU had head-to-head.
