Nevada has nothing like that going for it. The Wolf Pack are 1-4 in their last 5. They lost at home to Montana State, dropped a 3-point shootout to Air Force and beat UTEP for their only win in that stretch. The 31-17 loss to North Dakota State shows how these games keep getting away from them: Nevada led 11-0 early in the 2nd quarter, gave up a 100-yard missed field-goal return for a touchdown, and then fumbled a trick-play 2-point try that the Bison ran back for 2 points of their own.
There is some offense in Reno. AJ Bianco hit Gary Givens III for a 19-yard touchdown that got Nevada within 19-17 against North Dakota State, and the Pack put up 33 on Air Force. The defense is the problem. It gave up 36 to Air Force's option and 31 to the Bison, which is a rough résumé to bring against the best rushing attack in the Big Ten. If Nevada can't get stops on early downs, UCLA will just keep running and Dieffenbach won't have to do much.
The early forecast for Pasadena says 60 degrees with light drizzle and not much wind. That's 7 days out, so don't count on it. The Rose Bowl crowd is worth watching too: UCLA averaged only 32,978 through its first 3 home games and has started offering free student admission and buses from campus. Chesney took over a 3-9 program and has it unbeaten in Big Ten play. A 2-4 non-conference visitor in Week 10 is mostly a chance to get Dieffenbach more reps and keep everyone healthy.
