You already have another TE, WR, but he's playing OLB. Back when Julius Peppers was at Carolina, they had some plays for him on offense, not that they ever worked, but the idea looked good to have a 6'7" receiver in the red zone. He once intercepted a pass and returned it 97 yards without scoring; nobody caught him while he was running, but when he stumbled and fell at the 3 yard line, that ended it. He wasn't used to running that far at once I guess.
After Mingo accomplishes enough on defence, they might consider making more use of his energy.
