The Big Ten would do away with its championship game if college football adopts a 24-team playoff. Big Ten commissioner Tony Petitti says that’s a worthwhile sacrifice to get his preferred postseason format. Pettiti mentioned this possibility back in May as he stepped up his push to expand the current 12-team playoff to 24. He made the point clear Tuesday by conceding a 24-team playoff would mean no Big Ten championship game. The bid to expand the playoff to 24 teams also has the support of the Atlantic Coast Conference, Big 12 and Notre Dame. The Southeastern Conference remains a holdout.
