Lessons learned from Penn State's 45-21 win against Purdue in Week 12:
1. Fumbling issues aren't behind Zach Zwinak ... or Bill Belton: Zwinak fumbled for the fourth time this season Saturday -- even with the gloves -- while Belton lost his third fumble of the season. The Nittany Lions are among the most fumble-prone teams in the country and, despite constant emphasis on holding onto the ball, it's obvious that still remains an issue. They've both been great for PSU this season -- but with one large asterisk. Fumbles.
2. Changes could be coming on the kickoff team: The Lions surrendered a 100-yard kick return TD, the first time that's happened since Michigan State's Derek Mason pulled it off in 1994. And then it nearly happened again but, luckily for the Lions, Sam Ficken stepped up to take down the returner. As a result, Bill O'Brien said the staff will look into making some changes on that special-teams unit this week. Maybe, he mused, some guys just aren't hungry enough.
3. "Complementary football" isn't out of reach: O'Brien's squad performed the opposite of "complementary football" against Minnesota last week. But against Purdue? PSU forced three turnovers, and the offense converted each of those into a touchdown. When the offense needed the defense to step up, it did -- and vice versa. That's why, even when this game was just a one- or two-score game, it felt so out of reach for Purdue. PSU played a below-average opponent, but it still played relatively well. It should reach at least seven wins this season if it can keep that up.
4. The freshman linebackers still have quite a way to go: Redshirt freshman Nyeem Wartman missed a few tackles -- again -- and he's looked lost at times this season. True freshman Brandon Bell also saw more time than usual against Minnesota, and he's trying to get his feet wet because he could compete for a starting job next season. With Ben Kline's injuries, which require two separate surgeries, only Mike Hull, Wartman and Bell will be the returning linebackers with considerable playing time under their belts. Bell and Wartman are more important than ever now, and they could see more time in the final two games.
