Courtney Martinez | NCAA.com | September 24, 2015 UCLA-Arizona prepare for desert showdown and more in Week 4 Share Other stories to watch: Can Texas Tech continue its momentum against TCU? Texas Tech fans definitely remember the 82-27 thrashing TCU gave their football team in Fort Worth last year. But the Red Raiders have shown great signs of improvement especially in their road upset at Arkansas last week. Meanwhile TCU has had some of the worst luck with injuries on defense, which already lacked experience to begin with this season. So you can expect this game to be a lot closer than last year along with some serious implications in the conference. TCU has chance to show it's not going anywhere, while Texas Tech can prove it's a Big 12 contender. Versus: TCU Football-Trevone Boykin vs. Texas Tech-Football Patrick Mahomes Will Tennessee end its 10-game drought against Florida? The Vols bounced back nicely after their collapse two weeks ago to Oklahoma with a 55-10 win over Western Carolina last week. But, Tennessee faces a much tougher opponent in Gainesville this week, a place where the Vols haven't won since 2003. Tennessee has downplayed its history of frustration against Florida. So is this final the year for the Vols? It won't be easy because Florida has won 10 straight in this SEC East rivalry and last week stopped Kentucky from ending its losing streak. How will USC respond on the road after the loss to Stanford? After the 41-31 upset to unranked Stanford at home, the Trojans will look to avoid a 0-2 start in Pac-12 play as they face Arizona State. USC fans don't have to be reminded of the last time the Trojans were in Tempe where the Sun Devils dominated with a 62-41 win. Plus, the Sun Devils have won three of the last four in the series. USC entered the season as the Pac-12 South favorites, so this game will decide whether USC still can win the division or if it will sink further in the standings.
