PSU ends Wisconsin's BCS bowl hopes

You can't underestimate Penn State.

The Nittany Lions stepped into Camp Randall as a 24-point underdog, as a struggling team that had just 61 scholarship players and was was set to face the nation's No. 15 team. But these Nittany Lions have become accustomed to overcoming the odds, and they again shocked Wisconsin in a 31-24 upset.

Christian Hackenberg played his best game as a Nittany Lion, as the freshman quarterback completed 21 of 30 passes for 339 yards, with four TDs and no interceptions. On the other end of the field, Penn State's defense shut down Wisconsin's rushing attack (121 yards) and forced turnovers at critical junctures. It held off a late Badgers comeback and put an end to Wisconsin's hopes for a BCS bowl.

The upset replaces the win over Michigan as Penn State's biggest of the season, and it will certainly give Bill O'Brien's team something to build from this offseason.

This gives the Lions another winning season in the face of unprecedented sanctions, and it again sends out a senior class with a victory. Just about everyone was surprised with Saturday afternoon's upset -- except for O'Brien and Penn State's players.

When everyone counted them out, they came right back to prove everyone wrong. What else is new for this bunch?

Where the game was won: Penn State didn't turn the ball over once, and Joel Stave threw three interceptions -- two of which led to PSU touchdowns. The Badgers simply couldn't overcome those mistakes.

Key play: With less than four minutes left, PSU faced a third-and-9 at its 18. The Lions were up by just a touchdown, and momentum was shifting to the Badgers' side. But O'Brien called a draw play and Zach Zwinak gained 61 yards before he was tackled. That didn't give the Badgers much left to work with.

Record breaker: Allen Robinson (eight catches, 122 yards) finished his junior season with school single-season records for receptions (97) and receiving yards (1,432). The two-year starter is also second on the career receptions list and third on the career yards list. He has one year of eligibility remaining, but it seems likely he will declare for the NFL draft.

Curious calls: Gary Andersen called a season-high 53 pass attempts -- compared to just 30 runs -- and while a lot of that can be attributed to Wisconsin trailing, there's definitely some question marks next to the third-down play-calling. The Badgers were faced with seven third downs that required four yards or fewer, and Andersen opted to pass on all but one of those. Wisconsin twice passed on third-and-1 and converted just one of those attempts.

Looking to the future: Twenty-three freshmen (11 true, 12 redshirt) made the travel roster for Penn State, and quite a few made an impact. Besides Hackenberg, tight end Adam Breneman (three catches, 78 yards) played well, and linebacker Brandon Bell earned his first start. Penn State is a young team, and it certainly flashed some talent Saturday.
