Diaby plays with strong hands and clear eyes at the point of attack. He can strike and separate as a two-gapping five-technique or pursue and tackle as a 4-3 base end. He’s a power rusher lacking an instinctive approach to beat better NFL tackles, but his lateral quickness and short-area burst make Diaby perfect for a twisting/gaming front. His frame and skill set could attract attention as an odd- or even-front end with his ceiling being defined by how much he’s able to improve his creativity as a rusher.
