PASADENA, Calif. — Now that the guys putting together the College Football Playoff have determined where the games will be played, there’s only one major item left on the agenda — and it just might be the most important piece.

Who is going to pick the teams that play for the national championship and how will they go about it?

“It’s huge,” Pac-12 Commissioner Larry Scott said Wednesday. “Major change going from the BCS standing to a selection committee.”

Scott and the other BCS conference commissioners ended Day 2 of their meetings at the home of the Rose Bowl by announcing that Cowboys Stadium will host the first championship game in the new postseason system, and that the Cotton Bowl, Fiesta Bowl and Chick-fil-A bowls will be part of the six-game semifinal rotation.

Arlington, Texas, edged Tampa, Fla., in the bidding to be the site of the first championship game.
