Mack is a truck and believe me he hauls a full load. He is a big and powerful wide body that possesses exceptional strength and power in his upper body along with his hips. Bulldozes defenders off the line of scrimmage at times but tends to like to turn the defender other plays. Has a jolting first punch that often knocks the defensive man to the turf. Plays with good pad level despite size. When his legs and upper body work together he can destroy a defender and drive him into the lap of the linebacker. Even though foot agility can be improved, displays athleticism when pulling, trapping, and leading upfield. Shows some quickness and ability to adjust in the openfield. Very solid pass protector that stops the initial charge of the rusher with a jarring first punch and rarely gets over-extended. Shuffles feet well and maintains relationship with pass rusher and seems to be able to protect the inside slant move or the speed rush off he edge. Mack can develop into a fine offensive lineman at the next level once he improves overall quickness and flexibility. It would be tough to find anyone with as much strength and power as this guy. Plays with good effort and works to be sound at all phases of offensive line play. He also demonstrates very solid skills and fundamentals for such a raw talent. He has the chance to be a big time player.
