Strong performances at the NFLPA Collegiate Bowl and Senior Bowl practices have boosted Johnson's draft stock despite somewhat pedestrian tape. He has the build, strength and length to play as a defensive tackle or odd-front end. He flashes recovery strength to battle back against early disadvantages, but needs to get off the ball and into opponents more aggressively to create early advantages of his own. Johnson's week in Mobile gives him a chance to hear his name called during the draft.
