All I've really heard is from McElroy at media days. He says he impressed with the new receivers and in particular DeAndrew White. McElroy also says DeQuan Menzie is participating in the 7-on-7 drills at full speed despite tearing his ACL the last week of march...which I must say is simply incredible.
Speaking of McElroy, I can't remember where I heard it but I know it was from someone who's in the media and regularly around the team...but they said that McElroy has bulked up quite a bit in the off-season. Also, now that I remember, I've heard a lot about Julio as well. It's been said that he's going to be a different player this season, as in scary-good from team mates.
