I think a win over UCLA will get the fanbase excited for the upcoming season. It will also get BYU into the winner's bracket where they will likely play an elite Kansas team and likely another top 50 team (Dayton/Georgia winner) in the 3rd round. Georgia was ranked #45 in the rankings posted above and Dayton was #59.
BYU's experience may give them an edge as they look to get some big early season wins.
