It's never too late -- or too early -- to see what we learned from this season and also look ahead to next season. So, we've started breaking down each position on the Nittany Lions.
Up today: Offensive line.
Expectations entering the 2013 season: OL coach Mac McWhorter's group was expected to start fast, as it returned three primary starters and several other players who saw significant time in 2012.
LT Donovan Smith was a favorite on projected breakout lists, and John Urschel often said that center Ty Howle was the most underrated lineman on the team. The real question mark surrounded right tackle, and whether Adam Gress or Garry Gilliam could step up. With an extra year under McWhorter and strength coach Craig Fitzgerald, many believed this line would be as good -- or better -- than 2012.
How they fared: They didn't quite get off to the start they wanted -- even Urschel admitted that. Consistency was difficult to come by early in the season, and Smith certainly didn't live up to his potential. Bill O'Brien didn't start him for a game -- and that certainly appeared to send a message -- but this line played its best football at the end of the year.
Zach Zwinak rushed for 563 yards in the last four games. And, overall, PSU allowed 22 sacks on the season -- which isn't too bad considering a rookie was standing in the pocket and sometimes taking too long to throw the ball. This line played as expected in the second half of the season, but it was a different story in the first half.
What we learned: This line is pretty versatile. Left tackle and right tackle were relatively interchangeable, Angelo Mangiro could play anywhere along the interior and Eric Shrive could play anywhere outside of center. We saw this in 2012, but 2013 just reinforced it. When some players found themselves injured or in slumps, this line showed it was pretty flexible and able to adjust.
Grade: B. This a little tricky because the grade in the first six games would've been markedly different than the last six games. Overall, though, this line played above-average. Urschel was an All-Big Ten player who was selected as a third-team All-American by the AP. Gilliam was a pleasant surprise, Smith a disappointment, and everyone else played close to as expected.
Key losses: OG Urschel, C Howle, OT Gress. Gilliam still hasn't made up his mind on whether to stay. First, he was staying, then leaving ... and then he wasn't sure. His decision will have quite an impact on this group, however. If he leaves, PSU has to plug three openings on the line -- and right tackle will be the biggest concern of all since three of PSU's top four tackles would then graduate.
Position stock watch: Trending downward. Even if Gilliam stays, the offensive line is going to have a lot of question marks to overcome. Mangiro will be able to fill one spot along the interior, but who else will start? Wendy Laurent, who played in five games? And just think about that hole at right tackle if Gilliam does leave. It seems as if freshman Andrew Nelson might have to take over out of necessity. Depth is a thing of the past for this group.
Key to next season: Finding key contributors to add depth. For the last two seasons, PSU hasn't had to search long to find players who could give the starters a quick breather. But it's going to be a bit more difficult this offseason. Laurent, Anthony Alosi and Tanner Hartman have to add weight to their frames before they become viable options. (No lineman under 290 pounds saw significant time last season, and those three are all under 290.) And players who look the part -- such as 6-foot-4, 305-pound OG Brendan Mahon or 6-5, 297-pound OT Nelson -- haven't yet played a single snap. PSU is likely going to have to play some linemen who aren't quite ready, so they're ability to overcome the obvious learning curve will be paramount.
