Summary: Paul Crane and scout Dave-Te' Thomas look at three teams with all sorts of question marks as they get ready for training camp. The Pittsburgh Steelers have WR questions now that JuJu Smith-Schuster is the clear #1, RB questions, K and even coaching questions. Carolina Panthers QB Cam Newton still has questions surrounding his shoulder, while the rest of the offense has questions at virtually every position set. The defense has plenty of linemen, but who replaces Thomas Davis and questions in the secondary. The SF 49ers have questions about how well will Jimmy Garoppolo perform coming of his knee injury? Also what will the RB situation be like with Coleman/McKinnon, can Nick Bosa fit in on the field and locker room and should Richard Sherman move to safety? Also sleepers to watch for all three teams.
