Lessons learned from Penn State's 31-24 upset win over No. 15 Wisconsin in the season finale, its first win over a top-15 team since the Capital One Bowl victory over LSU in 2010:
1. Don't underestimate Penn State. You think we would've learned that by now. But after seeing the Buckeyes absolutely dominate Penn State, 63-14, it seemed as if PSU would be in for another flogging. Everyone counted them out -- Vegas put the line at 24 points -- but the Nittany Lions seem to do best when everyone else thinks they have no chance. They came out of absolutely nowhere to not just slip past the Badgers, but to totally outplay them. Penn State's defense stopped one of the nation's best rushing attacks, and freshman quarterback Christian Hackenberg picked on the Wisconsin secondary. If there's one thing we should learn from this game, it's that we should never count these Nittany Lions out.
2. The future looks bright. Next season should have its share of question marks, but even look past that. Hackenberg is playing beyond his years, freshman LB Brandon Bell garnered his first start (and grabbed six tackles), and PSU dressed 23 total freshmen. Adam Breneman and Eugene Lewis still have three years left and had terrific performances on Saturday. And then there are other freshmen such as Akeel Lynch, Richy Anderson, Nyeem Wartman, Austin Johnson and Malik Golden who have seen quite a bit of time this season.
3. Sam Ficken's struggles aren't behind him, after all. Ficken had a miserable stretch last season before he seemingly turned it all around -- but those issues are most certainly back. He has made just seven of his last 13 field goals (54 percent) and also missed a PAT last week. He went 1-of-3 against Wisconsin, missing a 31-yarder and 34-yarder, and he'll need to find more answers over the offseason. He's bounced back once already, but he'll need to find a way to do it again. Otherwise, freshman Chris Gulla could push him for time.
4. The offensive line needs to be more disciplined, as far as penalties. Either it wasn't prepared for Wisconsin's defensive linemen moving around or it wasn't focused. Whatever the reason, it was one of the odder sights during Saturday afternoon's game. Penn State was called for at least eight motion penalties, with left tackle Donovan Smith responsible for four of those. Offensive line coach Mac McWhorter was clearly frustrated on the sideline and, although the line played well overall, it certainly needs to concentrate more on the snap count and less on what the opposition is doing. Those mistakes nearly lost PSU the game.
5. Secondary, bad; front seven, good. Joel Stave had difficulty locating quite a few open targets, and that came as a big break for Penn State. The secondary still struggled, but it came up with key interceptions off Stave mistakes to somewhat atone. It's still clearly the weak link of this defense, but the front-seven -- especially the defensive line -- played very well yet again Saturday. They finished with five quarterback hurries and three sacks, and the line really limited the Badgers' rushing attack. Wisconsin was held to its second-lowest rushing total of the season (120 yards), and defensive coordinator John Butler deserves a lot of the credit. That should bode well moving forward.
