Can the Nittany Lions build off last season and play the role of BCS spoiler? Let's take a closer look at this 2013 Penn State team:
PENN STATE NITTANY LIONS
Coach: Bill O'Brien (8-4 overall, 8-4 at Penn State)
2012 record: 8-4 (6-2 Big Ten)
Key losses: QB Matt McGloin, C Matt Stankiewitch, DT Jordan Hill, LB Michael Mauti, LB Gerald Hodges, CB Stephon Morris
Newcomer to watch: QB Christian Hackenberg. He was the top-rated quarterback in the 2013 class, and ESPN ranked him as the 15th-best high school prospect in the nation.
Biggest games in 2013: vs. Michigan (Oct. 12), at Ohio State (Oct. 26), vs. Nebraska (Nov. 23), at Wisconsin (Nov. 30)
Biggest question mark heading into 2013: O'Brien turned this passing offense around last season with an up-tempo style and an efficient McGloin, who tossed 24 touchdowns to five interceptions. But he'll have to start a first-year QB this season, as none of PSU's five signal-callers -- three walk-ons, two on scholarship -- were on the roster last season.
The race is between Hackenberg and Tyler Ferguson, a junior college player who missed about a month of voluntary workouts. O'Brien plans to name a starter about midway through camp. Whoever it is, he will have to learn quickly for the Nittany Lions to repeat the success of last season.
Forecast: Penn State overcame some huge question marks last year and went on to have a surprisingly successful season, but it's not going to get any easier in 2013.
The defensive front seven is short on depth and bigger on inexperience. Nyeem Wartman, a redshirt freshman, will take over for a Butkus semifinalist at linebacker. The starting DT opposite Jones -- projected to be Kyle Baublitz -- compiled just three stops last season and weighs in at just 281 pounds. A single injury at either spot would be devastating for the Nittany Lions.
On the bright side, there are clearly some strong leaders who could make up for some early missteps. Barnes was last year's Big Ten Freshman of the Year, and he's already one of the league's most feared pass-rushers. Hull is poised for a breakout season, and teammates recently called his offseason improvement the most impressive.
But out of all the defensive stars, Amos might surprise fans the most. He moved from cornerback to his natural position at safety in the offseason, and last year's 50th-ranked pass defense should be better this time around.
On offense, just about every unit has improved, with one big exception at quarterback. It'll be difficult for any newcomer to match McGloin's performance, but there's a strong supporting cast. Robinson is the top wideout in the Big Ten, Zwinak reached the 1,000-yard plateau last season, and the tight ends will play as large a role in this offense as any other team in the country.
In short, like last year, PSU is a bit of a wild card. If it receives strong efforts from its quarterback and the front seven, it should surpass last year's record. If it doesn't, it might be fortunate to get to seven wins.
