Here's the latest on the situation:
I can confirm via multiple sources that Pitt sophomore running back Rushel Shell is indeed considering a transfer from Pitt. He could certainly still change his mind, but he's at least very heavily weighing the decision. As of this morning, he had not requested formal transfer paperwork, which would be the first step in the process.
I've heard several different reasons for the decision, so it's probably a combination of factors. The factors that drew Shell to Pitt in the first place, specifically the proximity to his family and his young daughters, are still in play as reasons he could pull a last-minute switch and stick around.
Shell missed practice Tuesday with "an excused absence" that did not appear to be related to the leg injury he suffered in Friday's scrimmage. When asked after practice, Pitt coach Paul Chryst said Shell had "a couple of things" he needed to work through. The Panthers will practice again tomorrow, with Chryst slated to speak to the media afterwards, so it's doubtful the situation would stay in limbo any longer than that.
If Shell does elect to leave, it opens a massive void in the Panthers' offensive backfield. Shell rushed for 641 yards and four touchdowns on 141 carries as a freshman in 2012 and was slated to be the unquestioned starter and workhorse back in 2013. His departure would propel junior Isaac Bennett into the top spot on the depth chart with Malcolm Crockett assuming the No. 2 spot. That duo combined for 41 carries and 191 yards in 2012.
