Among format changes being considered by Bowl Championship Series members is an informal proposal that would radically change the structure of the BCS and significantly alter the major bowl selection process. The suggested change calls for the BCS to sever its direct ties with the so-called BCS bowls -- the Allstate Sugar Bowl, Tostitos Fiesta Bowl, Discover Orange Bowl and Rose Bowl Game presented by Vizio -- and concentrate solely on arranging a No. 1 vs. No. 2 national championship matchup, according to sources. In addition, the BCS title game could potentially be bidded out to nontraditional sites, such as Cowboys Stadium.
