Gerhart is a thick, physically put-together running back with a powerful lower half and a well-built upper body. He isn't an explosive athlete, but he has an above-average first step and gets up to speed quickly when pressing the line of scrimmage. He lacks a second gear to his game and isn't a threat in the open field, but he runs with impressive power once he reaches full speed. He does a nice job of dropping his pad level and churning his legs through the line of scrimmage and loves to finish runs, always falling forward. Gerhart possesses good vision and patience at the line of scrimmage and looks comfortable allowing his blocks to set up and then running to daylight. He's a better one-cut athlete than he's given credit for and has the ability to sidestep tackles in space and create after contact. He possesses some cutback ability at the line, and that, paired with his lower body power, is very tough to bring down on contact. He has the ability to consistently step through arm tackles and can wear down the opposing front seven. But he isn't quick or sudden and fails to create on his own. He lacks the type of wiggle to make a man miss and struggles to get back up to speed quickly once he stops moving his feet, which also takes away from the impressive momentum he can build. Gerhart does a great job picking up blitzing linebackers in the pass game and does a nice job as a blocker. He isn't a featured back at the next level, but he looks like a guy who can batter an opposing defense and work his way into a nice role as a No. 2 power back who has the ability to play on third down.
