DEPTH CHART FEATURES - What Ourlads NFL Scouting Services said before DAVID JOHNSON made the Arizona Cardinals' depth chart: Northern Iowa, 6006, 224, 4.46. Fifth year senior and a four-year starter from Clinton, IA. Rushed for over 1,000 yards three straight seasons and leaves Northern Iowa with almost every school rushing record. He also caught 141 passes. Johnson is an upright runner with good speed and receiving ability. He doesn’t show the quick twitch and reaction between the tackles, but he has a high ceiling considering his tool set and ability to change direction with balance. His future may reside as a third down back and return specialist with the upside to be much more. Quick off the snap, can eat up a 10 yard window in a blink. Natural feel with the ball in his hands. Runs with good awareness and vision. Shows balance and body control in traffic. Can change direction with ease. Elite ball skills as a receiver. Can reach for the ball away from his body on the move. Has the speed to run away from defenders in space. Aggressive, physical presence as a ball carrier and blocker. Plenty of yards after contact. Lacks the lower body thickness to take the amount of hits he will encounter with his height and running style. 2014 stats: 1553 yds, 5.4 ypc, 17 TD, 38 rec, 536 yds, 2 TD. OSR:1/ 34. Third/fourth round. (A-31 3/8, H-9 5/8, BP-25, SS-4.27).
