GREEN BAY — He won’t even have to change team colors. The Pittsburgh Steelers have drafted Iowa running back Kaleb Johnson in the third round of the NFL Draft. The Steelers, who chose Defensive Tackle Derrick Harmon in the first round, did not have a second round selection. Johnson is listed at 6’1″ and 224 pounds. He ran a 4.57 40-yard dash in the NFL Combine. Steelers Offensive Coordinator Arthur Smith called Johnson, a“Perfect fit. Regardless of whatever run scheme he is running — he ran multiple in Iowa — (he is) really impressive as a volume runner as the game went on. One of the more impressive stats you’ll see (is) what he averaged in the fourth quarter. I believe it was over five yards per carry. It might have been closer to six. We think he’s a great culture fit.”
