Jackson is an edge defender who plays with some firmness into contact but is lacking in quickness and athleticism. He doesn’t have much arm length, so he can absorb blocks with balance but struggles to get off of them quickly. He doesn’t have the short-area movement as a run defender or pass rusher to make many plays in the backfield, but he can dart off the snap and get into gaps at times. He’s had a history of injuries and his athletic testing was unimpressive, so he faces an uphill battle to earn a spot in the league.
