Harold is a quick starter off the ball with natural burst out of his stance and an active play style to attack blockers. With quick footwork, he is a pesky defender to block in space and does a nice job with his upper body to extend and lock out, putting linemen on their heels. Harold has a lean build with minimal bulk on his frame and needs to develop his functional power for the next level to better match up on the edges as a run defender. He also tends to rush too upright, negating his flexibility or leverage, allowing blockers to engulf and overwhelm him.
