A lot of things need to go right for Pitt to have a decent season. Here is how I see each unit right now...
QB - Obviously it's frightening that Savage hasn't thrown a pass since 2010. The talent is there though, and we saw what Chryst and company did with Tino in terms of making better decisions and cutting down on his INT's, so it is possible that TS has a very serviceable year.
RB - Tons of questions here. The loss of Shell and Bennett's injury have crushed any depth that they had. Hopefully Bennett's injury isn't too serious and they can get some contributions from Conner. From what it sounds like, Conner would start if they played FSU today.
TE - Hands down the best unit on the offensive side of the ball. They can give defenses fits with a 3 TE set of Holtz, Garner, and Orndoff since all of them came get open down field.
WR- After Street, there are a lot of questions. It is pretty surprising that none of the upper classmen (such as Tinker, Weatherspoon) have seized the opportunity to take the other starting spot. On the other hand, it is promising that Boyd has beaten everyone else out and is currently getting the most reps opposite of Street. Like we all had hoped when he signed at Pitt, it appears that he is going to be special. Imagine if Pitt had landed both Foster and Boyd. An empty set consisting of Street, Foster, Boyd, Holtz, and Garner would have been fun to watch.
OL - Lots of inexperience and question marks, but I have faith in what Hueber can do with these guys. Bisnowaty appears to be a star in the making, and Clemmings has done well making the transition from the defensive side of the ball. It will be interesting to see if Dorian Johnson plays this year, or if he red-shirts. I would guess barring injury, he takes a RS.
DL - Donald and Ezell should be beasts in the middle, but they need production from Murphy and Durham at the ends. They really cant afford to lose Donald or Ezell though, as all of their depth behind them are true or RS freshman.
Linebackers - I expect them to be better than any group that Pitt has had in a while. Gordon is solid in the middle. Gonzalez shouldnt make you notice him in a bad way. Looks like Bam Bradley is pushing for playing time at the other outside spot. I would think that Thomas will earn his way back into the starting lineup over Bradley, and that will give this unit a huge boost. Plus, you have Ejuan Price, who is lining up at end now, but I would guess will be on the field during all passing downs as a hybrid DE/OLB pass rusher.
Secondary - Love Pitts, Williams, and Hendricks. I think the three of them are good enough to cover up for how slow Vinopal is. Trenton Coles has had a good camp, and is in line to be the 5th defensive back. The nice thing about this unit is that Pitts and Williams are so good one on one, it should allow House to blitz more linebackers and defensive backs since the two of them rarely need help covering.
Special Teams - From what I have read, Chris Blewitt has the leg to be one heck of a college kicker. Though Lieutenant Dan is an upgrade over Kevin Harper. Still, it is pretty fitting that Pitt has a kicker named Blewitt.
I am guessing they will finish somewhere between 5-7 and 7-5.
