The Rose Bowl will celebrate its 100th game on New Year's Day in 2014 as college football's oldest bowl. To mark the occasion, the game trophy has been modified by Tiffany to add 24-karat yellow gold vermeil accents to the 21-inch tall design that includes a three-quarter size sterling silver football. It was unveiled Tuesday at the iconic stadium, where the logo for the 2014 BCS national championship game was already on the field. Big Ten commissioner Jim Delaney and his Pac-12 counterpart Larry Scott stressed that both leagues were unwilling to sign off on any changes that excluded the Rose Bowl in the new postseason system that begins next year. Scott says the Rose Bowl is "the holy grail of college football." The stadium will host the last national title game under the current BCS configuration on Jan. 6.
