Arizona quarterback Khalil Tate, right, rushed 26 times for 161 yards last year vs. USC.

Here are three things to watch in the Arizona Wildcatsโ€™ game vs. USC at Arizona Stadium (Saturday, 7:30 p.m., ESPN2), plus a score prediction and some pertinent preview links:

1. ONGOING TATE DEBATE

Will this be the week? It seems like weโ€™re asking the same question every Saturday. Everyone continues to wonder whether the Khalil Tate of 2017 suddenly will reappear. Consider: Tate carried the ball more times against USC last year (26) than he has in four games this year (23). That he has just 31 net rushing yards โ€“ after running for 1,411 last season โ€“ is one of the most befuddling statistics in all of college football. If youโ€™re an Arizona fan, you obviously want to see the โ€™17 version of Tate show up. But itโ€™s tricky: You also donโ€™t want him to play โ€œhero ball.โ€ He wanted to beat the Trojans so badly last year that he forced a pass that was intercepted after USC took a late 42-35 lead. Tate was so emotionally invested โ€“ and so spent โ€“ that he cried on the field after the game. That sort of want-to hasnโ€™t been evident in Tateโ€™s running decisions so far this season. Maybe itโ€™s the ankle. Maybe itโ€™s something else. Maybe itโ€™ll come out against the school thatโ€™s in his backyard and features a handful of his former high school teammates.

2. RUN IT BACK

USC hasnโ€™t run the ball well or frequently, but thereโ€™s a strong suspicion that will change tonight. Although Arizona shut down Oregon Stateโ€™s run game last week, thatโ€™s been the exception. Each of the Wildcatsโ€™ first three opponents rushed for at least 183 yards. The UA defense might be the biggest reason Ronald Jones II landed in the second round of this yearโ€™s NFL draft. In three games against the Wildcats, Jones rushed for 448 yards and five touchdowns. USCโ€™s average output in those games looks like an accounting error: 293.3 yards. This yearโ€™s Trojans are averaging just 110.2 net rushing yards per game, an astonishingly low total that ranked 10th in the Pac-12 entering this weekend. Itโ€™s not as if USC lacks talent in the backfield. Stephen Carr, Acaโ€™Cedric Ware and Vavae Malepeai are averaging 5.5 yards per attempt. Itโ€™s just that none has more than 33 attempts through four games. If theyโ€™re smart, USCโ€™s coaches will resist the temptation to have JT Daniels chuck the ball all over Arizona Stadium, even though the Trojans have an advantage on the perimeter. The Wildcats, meanwhile, should invite that, no matter the Trojansโ€™ tendencies till now.

3. TRICK OR TWEET

Arizona pulled off a fake field goal last week. Do the Wildcats have more tricks in store for USC? Do they need to do something like that to win? Donโ€™t be surprised if Arizona attempts something a little out of the ordinary in a matchup that favors USC on paper (at least in terms of recruiting rankings and recent head-to-head results). It doesnโ€™t have to come on special teams, although winning that aspect of the game would go a long way. Something strange is bound to happen in Arizonaโ€™s first true foray into #Pac12AfterDark territory this season. (The UAโ€™s first two home games also were at night, but neither was against a conference opponent.) It might come in the form of a turnover, or several. I wrote earlier this week about the Wildcatsโ€™ dearth of takeaways. They have just one so far. The Trojans have just two. Those numbers arenโ€™t sustainable. In the past two meetings, Arizona has turned the ball over seven times to USCโ€™s one. Itโ€™s safe to say the Wildcats wonโ€™t win if theyโ€™re in the red again.

FINAL SCORE: USC 34, Arizona 27
