Oregon squared off against defensive coordinator Jim Knowles twice last season when he was at Ohio State with mixed results. Now Knowles is at Penn State after bolting the Buckeyes for a three-year contract worth more than $9 million. “I’ve seen a lot of scheme variation, which he (Knowles) had at Ohio State,” Lanning said Monday night, “but it’s a lot of the similar scheme they carried at Ohio State. With Knowles guiding the defense, Penn State has held Nevada, Florida International and Villanova to 17 points, including 14 that came in the final seconds in two games. They’re really good.”Lanning said that wide receivers Kyron Hudson, Trebor Pena and Devonte Ross have made an impact at Penn State after transferring there earlier this year.
