The Pitt football roster on the athletics department's website has been updated for 2016. These sorts of things are usually announced with little fanfare (if at all). Previously, the spring roster was up there, but the new one displays the current roster for the fall, which is different since it includes any new departures as well as incoming freshmen not enrolled early.
Chris Peak of PantherLair had many notable observations sprinkled on his Twitter account in regards to uniform numbers and new player weights of guys bulking up a bit. One noteworthy mention is that wide receiver Tre Tipton earned a redshirt for last season despite playing in four of Pitt's games.
Tipton's current bio mentions the knee injury sustained last year in practice and confirms that he received the medical redshirt. He played early in the year but not beyond the team's first four games. As I mentioned earlier this summer, he's part of a very deep receiving corps where there's going to be a lot of competition with some unknowns heading into the season.
We don't yet know how good Tipton can be but whenever you get a medical redshirt for a guy that played in several games as a true freshman, it's a good deal for both the team and the player. Tipton was a pretty significant recruit, picking the Panthers over Michigan State and others. He was also the Post-Gazette's Co-Male Athlete of the Year before coming to Pitt last season. He has the chance to develop into a good target and having for an extra season is a nice bonus.
