NCAA Division III playoffs

What: Wabash (Ind.) at St. Thomas in quarterfinals

When: Noon Saturday

Key players: Running backs Mason Zurek of Wabash and Jordan Roberts of St. Thomas. Zurek has rushed for 1,939 yards (6.7 yards/carry) and 22 touchdowns, Roberts for 1,640 yards (5.9 yards/carry) and 28 TDs.

The key: Can Wabash's undersized but athletic defense — the starting defensive line averages 241 pounds — contain St. Thomas' physical ground game behind an offensive line that averages 306 pounds?

Did you know? Wabash coach Eric Raeburn was an assistant at Division III powerhouse Mount Union, his alma mater. Raeburn has a 78-12 record in eight seasons at Wabash.
