As part of an ongoing series, NittanyNation will preview a different position leading up to the season opener against Syracuse on Saturday. Up today: Offensive linemen.
Key losses: RT Mike Farrell and C Matt Stankiewitch
Next in line: The Nittany Lions will use a rotation again this season, with Angelo Mangiro as the next man up when it comes to the interior. At tackle, Eric Shrive and Garry Gilliam will compete for time. (Shrive is also versatile enough to play inside.)
What to expect: With another season under OL coach Mac McWhorter and strength coach Craig Fitzgerald, this line should take another step forward. Sure, the loss of Stankiewitch and Farrell hurt -- but Howle isn't that much of a downgrade and Smith is healthy for a change.
If the right tackle (Gress or Gilliam) can get off to a good start, this line will be better than last season. Smith could be the next great lineman at Penn State, and the interior is very strong. As a result, Zach Zwinak should see plenty of holes inside and the running game should improve.
This group isn't entirely bigger weight-wise -- Gress, Howle and Dieffenbach lost weight from last season -- but don't let that fool you. This group is stronger, literally, from last season and should push around opposing defensive linemen a bit more.
Recruiting trail: In-state product Noah Beh (Scranton, Pa./Scranton Prep) is the lone offensive lineman of the 2014 class right now, and he won't make an instant impact at Penn State. He's no more than 260 pounds, so he'll need some time to fill out.
On the plus side, he can also play on the defensive line. And he has a lot of upside. Next season, however, could be the "Year of the Offensive Lineman" for Penn State.
PSU could take about three prospects there, and it's already extended offers to more than a half-dozen players -- including the likes of ESPN Junior 300 prospects Sterling Jenkins (Pittsburgh, Pa./Baldwin), Tristen Hoge (Pocatello, Idaho/Highland), Ryan Bates (Warminster, Pa./Archbishop Wood) and Richie Petitbon (Washington, D.C./Gonzaga).
Best-case scenario: At least three linemen earn All-Big Ten honors, as Smith breaks out and earns a reputation as Levi Brown's heir apparent. The line takes great strides, further increasing the legend of the crazy-in-a-good-way strength coach. (He wears shorts in 20-degree temperatures, does the worm before some games and once licked the gym floor to fire up his players.) Fans can breathe easy in future years knowing the linemen are in the hands of Fitzgerald and McWhorter.
Worst-case scenario: The right tackle is a big letdown and creates havoc along the line, while Smith shows himself to be injury prone. The interior is still good, but the tackles struggle without Smith and don't give the quarterback much time to throw.
Top position question: How does Donovan Smith compare to Levi Brown? Well, the last staff sure thought they were similar -- because that was one of the Nittany Lions' big recruiting pitches.
Former PSU coach Bill Kenney playfully pulled aside Smith's seat during a recruiting trip in 2010, telling him it was Brown's seat. The two were both initially recruited to play the defensive line, and Kenney showed Smith some clips of the 2007 first-round NFL draft pick.
Brown, 29, is currently listed at 6-6 and 324 pounds. Smith is 6-5, 322. And Urschel previously hinted that Smith held more potential than second-round pick Stefen Wisniewski. So Smith certainly has the potential to follow in Brown's footsteps.
