The Jaguars are expected to try Mohamed Massaquoi at slot receiver in training camp, where he'll compete with Jordan Shipley. Massaquoi looked like a future vertical threat as a rookie, but his play speed has since diminished and he's not a physical player. We expect he'll be a tough fit in the slot. As the roster currently stands, Justin Blackmon and Cecil Shorts are the Jaguars' starters with Massaquoi and Shipley as Nos. 3 and 4.
