Penn State released an updated depth chart today and, although quarterback remains a question mark, some positions certainly became clearer.

Here's a closer look at some of the notable changes:

1. Lots of movement in the secondary.

Adrian Amos is the top DB for the Nittany Lions, and he shined at cornerback last season. The versatile player practiced a lot at safety this offseason, though, and the depth chart now lists him as a starting safety alongside ... well, apparently, the other starter still isn't a lock.

Stephen Obeng-Agyapong, who started last season, is listed as Amos' backup. The other starter isn't yet decided, as Bill O'Brien put the "OR" next to Malcolm Willis' name, meaning a competition is still under way between him and walk-on-turned-scholarship athlete Ryan Keiser.

At cornerback, which saw Amos and the graduated Stephon Morris as the 2012 starters, there are two new names to watch. Sophomore Jordan Lucas grabbed one starting spot, while wideout-turned-corner Trevor Williams is listed at the other. Da'Quan Davis is Lucas' backup.

2. TE-turned-OT Garry Gilliam is now up to 305 pounds.

That's a huge turnaround in less than a year. He played the role of blocking TE last year and started the season at 262 pounds. So, in about 10 months, he's gained 43 pounds. That says quite a bit about PSU's strength and conditioning program. He's currently listed as Dononvan Smith's backup at left tackle.

3. Kyle Baublitz will start alongside DaQuan Jones at DT.

Redshirt freshman Austin Johnson received a lot of praise over the spring, and he seemed poised to grab the starting spot. But the more-experienced Baublitz is instead part of the first-string lineup.

Baublitz played in six games last year, and the most recent roster puts him at 286 pounds -- 32 pounds lighter than Jones and 11 pounds lighter than Johnson. He had two tackles and one sack last year.

4. The long-snapper is ... MLB Glenn Carson?

At least for now, it is. Sean Corcoran is an incoming run-on who's expected to compete for the starting snapping jobs, so Carson's name there could be short-lived.

5. Bill Belton remains the No. 2 RB, while Brandon Moseby-Felder will still start opposite WR Allen Robinson.

Neither was a big surprise, but there were questions surrounding both players. Akeel Lynch is the no. 3 RB, while Eugene Lewis-Matt Zanellato are the receiving backups. (Lewis should still see a considerable amount of time on the field, obviously.)

Moseby-Felder nursed a leg injury last season, which slowed him down in the early going, and he could be a nice surprise this season. Early enrollee Richy Anderson might have garnered his share of pats on the back, too, but he's listed as a fourth-stringer. A redshirt could be in his future.

6. Charles Idemudia is the non-scholarship LB to watch.

Yes, the starting lineup is still Mike Hull-Carson-Nyeem Wartman ... but that was never really in doubt. With just five scholarship linebackers on the roster -- six once Brandon Bell gets on campus -- a walk-on was poised to see some time.

PSU's players threw around a couple names, such as Adam Cole and Matthew Baney, but Idemudia is the only non-scholarship LB listed on the depth chart.

7. Kick/punt returners listed.

PSU tried a few different players on special teams last season. But as of now Belton and Alex Kenney are listed as the top-two kick returners, with Jesse Della Valle as the top punt returner. Those three had the most kick/punt returns last season, so it's not a huge shock to see those names again. One interesting change, though? Anderson is the No. 2 PR.
