Not specific WR's, but IIRC they mentioned the RB, Smothers. Brice also mentioned that Pitt has some nice Defensive Lineman and said it in a way that sounds like he has some inside info. He didn't mention any names, specifically, but he's almost certainly talking about their DT's. Pitt has 2 DT's, Nick James and Sean FitzSimmons, who are both redshirt juniors and have both been named to at least 1 weekly All-ACC PFF team. My guess is Nick James. Prister said they need to bring in at least 2 DT's.
Last year they mentioned that Admissions would be more lenient with taking undergrad transfers who aren't just true freshman from ACC and Big Ten schools, and they ended up bringing in Hughes from a Big Ten school (USC). I'd be very surprised if they didn't do their due-diligence on Marsh. If there is a realistic chance they can get him through Admissions, I have no doubt they'll do everything possible to entice him to hit the portal.
