Steelers RB Najee Harris is currently tipping the scales at 244 pounds, according to The Athletic's Mark Kaboly. "He’s all quads and hamstrings," Kaboly adds. Harris was 230 pounds at last year's Combine, so it's a significant gain. We tend to not like when RBs add weight, although it's less of a concern for a volume, power back like Harris. Still, we'll be keeping an eye on him this summer.
