Thus far the Trojans have had advantageous matchups in the NCAA Tournament. All three wins were by double figures against two undermanned teams (Kansas and Drake) and a familiar Pac-12 opponent (Oregon). That changes tonight against a Gonzaga team that is too proficient for the Trojans' zone defense. Expect the Bulldogs to rattle USC early and pull away in the second half. Play Gonzaga.

USC’s frontline can disrupt any team in the nation. Much like Oregon State, the Trojans found themselves in the last three weeks. While I have skepticism of betting against undefeated Gonzaga (only 15-12 ATS), the USC defense allows only 38.6 percent shooting, and I see the Trojans' size altering the Zags' shots. I'm banking on USC forcing the Zags into an alternate game plan. I took the points with the Trojans.

I think the Trojans match up fairly well with the Zags. USC will be the toughest test for the undefeated juggernaut so far in the tourney. This should be a closer game than the line suggests, so take the points.

No. 6 USC vs. No. 1 Gonzaga from West Region. The third spot in the Final Four is up for grabs Tuesday, and while I'm sure the unbeaten Bulldogs stay that way, this will be competitive. USC ranks No. 1 nationally in two-point field goal defense and has a stellar paint protector/shot-blocker in Evan Mobley. Gonzaga largely lives inside the three-point arc/in the paint. Also, for what it's worth: USC beat BYU this season by 26 points, which is a significantly bigger margin than Gonzaga beat the Cougars in any of their three WCC meetings. Bet against Trojans coach Andy Enfield (10-0 ATS in NCAA Tournament career) at your peril.
