Ask Pitt coach Paul Chryst to go through a position-by-position rundown of his team, and you likely are to hear a lot of questions.
That's fine for now, but Chryst has just four weeks to find some answers for the uncertain spots on his roster.
Pitt opens its second training camp under Chryst today and will use the time between now and the season opener Sept. 2 against Florida State to fill in the depth chart.
Though there is plenty of uncertainty, Chryst also sees opportunity.
"There are a lot of questions," he said Monday. "But not all of them are negative like, 'Boy, we've got to get that answered.' "
Most of the position battles are on the offensive side of the ball, where the Panthers return only four starters from2012, and two of them are changing positions.
Along the offensive line, Matt Rotheram and Cory King -- starters at tackle in 2012 -- will move inside to occupy the guard spots. Redshirt freshman Adam Bisnowaty has a firm hold on the starting left tackle position, but right tackle is wide open.
Redshirt senior Juantez Hollins, redshirt junior T.J. Clemmings and true freshman Dorian Johnson will battle for the position. Hollins was suspended in 2012, Clemmings moved over from defensive end in December and Johnson is just three months removed from his high school graduation.
"It's truly three different unknowns," Chryst said.
Chryst also said he expects a bit of competition at center between redshirt freshman Gabe Roberts, who got all of the first-team snaps in spring practices, and redshirt sophomore Artie Rowell.
"I like the position a lot more than I did last year at this time," Chryst said of the offensive line as a whole. "But probably more question marks right now than last year at this time."
And there is the question of which quarterback the offensive line will be protecting. Chryst hasn't named a starter between redshirt senior Tom Savage and redshirt freshman Chad Voytik, though Savage appears to have an edge heading into training camp.
"The biggest thing we talk most about is we've just got to make sure both of them are ready to go," Chryst said. "We've got to help develop them and that's really all we're concerned about."
Those quarterbacks need targets to throw to and, beyond redshirt senior Devin Street, the Panthers are lacking in terms of proven options at wide receiver.
The second receiver position likely will come down to a battle between redshirt senior Ed Tinker, redshirt junior Kevin Weatherspoon and true freshman Tyler Boyd. Redshirt freshman Chris Wuestner and true freshman Zach Challingsworth also could factor into the mix.
"I think all those guys, that's probably the most open of the spots on offense, probably on the team," Chryst said.
Chryst also said he expects some help from the tight ends in the passing game, particularly redshirt junior Manasseh Garner, who transferred from Wisconsin and sat out in 2012.
"Let's see who emerges or even what kind of combination of guys can emerge at the wideout," Chryst said. "[Former receiver Mike Shanahan] was an every-down [receiver]. You don't have to replace Shanny, but can Manasseh and Tyler or [Tinker] replace that?"
That's one question, along with many others, that Chryst will hope to have answered over the next month.
NOTES -- Wide receiver Ronald Jones and defensive lineman Khaynin Mosley-Smith have been suspended for the 2013 season, Chryst said Monday. Jones was suspended for a violation of team rules and Mosley-Smith's was an extension of his indefinite suspension for an April arrest. Both players can practice with the team while suspended. ... Chryst also said freshman quarterback Tra'von Chapman remains on indefinite suspension. Chapman was arrested in May for assault and pleaded guilty to the charges last week. He served three days in jail, and Chryst said his status with the team is still being evaluated.
