When No. 3 Penn State and No. 6 Oregon take the field in Happy Valley on Saturday, the most interesting chess match will be between Jim Knowles and Will Stein.
Penn State first-year defensive coordinator Jim Knowles got two cracks and Oregon OC Will Stein and the Ducks last season. Stein got the best of him in Eugene in Week 7, but at the Rose Bowl, in the College Football Playoff Quarterfinal, Knowles figured the Oregon offense out.
