San Diego excelled last year despite having a very young team, and won a NCAA game out of a No. 13 seed with a roster that included seven freshmen — it’s a big reason they’re heavily regarded again in the WCC this year. Instead of relying on a boatload of seniors, last year’s Toreros did it with a strong policy of stopping 3s and forcing turnovers. And that’s the M.O. in the northernmost outpost of the CAA, which in five games has allowed just 21.7 percent of 3s to fall and have abruptly ended 25 percent of opponent possessions in turnovers. And it may not be UConn, but the Huskies have already beaten Providence this year.
