WASHINGTON -- A House subcommittee approved legislation Wednesday aimed at forcing college football to switch to a playoff system to determine its national champion, over the objections of some lawmakers who said Congress has meatier targets to tackle.

The bill, which faces steep odds, would ban the promotion of a postseason NCAA Division I Football Bowl Subdivision game as a national championship unless it results from a playoff. The measure passed by voice vote in a House Energy and Commerce Committee subcommittee, with one audible "no," from Rep. John Barrow, D-Ga.

"With all due respect, I really think we have more important things to spend our time on," Barrow said before the vote, although he stressed he didn't like the current Bowl Championship Series, either.

The BCS selections announced last weekend pit two unbeaten teams, No. 1 Alabama and No. 2 Texas, in the Jan. 7 national title game. Three other undefeated teams -- TCU, Cincinnati and Boise State -- will play in a BCS bowl game, but not for the championship.

"What can we say -- it's December and the BCS is in chaos again," said the bill's sponsor, Rep. Joe Barton of Texas, the top Republican on the House Energy and Commerce Committee. He said the BCS system is unfair and won't change unless prompted by Congress.

The legislation, which goes to the full committee, would make it illegal to promote a national championship game "or make a similar representation," unless it results from a playoff.
