If all goes as planned, Lotulelei and Short will become defensive building blocks, bringing complementary skill sets to the Panthers' defensive line. Once viewed as a potential top-five pick, Lotulelei's stock dropped, apparently because of concerns about pass-rushing ability and a heart-efficiency scare at the NFL Scouting Combine. On the positive side, Lotulelei was billed as the strongest run defender in the draft, with the ability to occupy multiple defenders and make plays in the backfield.
