    Functional Athleticism - His general mobility is pretty strong, a redeeming quality when considering his limitations in power. Lateral slide and quickness should offer him some level of appeal in outside zone heavy rushing offenses and he's an effective mover in space.

    Football IQ - He's guilty of some lapses in both hand and footwork and he can be overwhelmed when he's giving up his initial gap. Struggled at times with the simple tasks, too — like snapping. Was rolling back snaps at the Shrine Bowl at practice too many times to count. Troublesome trends for a long-tenured starter.

    Anchor Ability - Functional strength as a whole is underwhelming and he doesn't offer a lot of power when he sets his hands. He's lacking in the lower body strength to squat, drop the hips and eat up rushes and his alternate methods give too much ground — power linemen and twitchy linemen will both pose challenges.

    Hand Technique - His strike timing isn't bad but his strike zone in general is small because of short arms. He will struggle to manipulate bodies away from his frame and his footwork lapses expand upon and compound his issues of stickiness at the point of attack.

    Balance - When he's unattached, he moves cleanly and will redirect himself well. Carries himself and gears down momentum effectively to square up blocks. Issues arise when he lets his feet die on contact — which is too often. Those instances result in him sliding or falling off the block and conceding penetration.

    Pass Sets - He's light on his feet and appreciate his mobility to slide and set himself — but his sets are collapsed quickly and broken down due to a lack of anchor and inability to throw the ebrake. He's pretty savvy regarding twists and exchanges thanks to his experience starting on the line at Texas — not often tricked.

    Flexibility - Plenty of fluidity throughout his frame, he's a clean mover both out of his stance and when he's faced with flashing penetration that requires him to flip his hips and greet defenders in the gap. Shows good pad level, too — he's just out-gunned by power and defenders who carry momentum into the LOS.

    Power at POA - You're not going to have much success asking him to drive nose tackles off the football. He'll have some success on chip and combo blocks to bump DL out of gaps before stepping up to the next body and getting attached. He's not a mauler and will need heavy handed OGs to help him kick start push.

    Length - 31" arms are problematic and often complicate his reps, even when he's framed blocks well. Will get out-reached by long-armed interior defenders and does not have much at his disposal to dissuade stacking of his blocks — effectively transitions into "along for the ride" role once DL gets hands extended.

    Competitive Toughness - Needs to get stronger, point blank. Not sure how much ceiling there is here for him to grow upon four years at Texas but lower body power should be considered top priority once he hits the next level. Can't afford to catch bodies and not have the core and leg power to stall those upfield charges. 


    Best Trait - Lateral Mobility

    Worst Trait - Power at POA

    Red Flags - None

    Player Summary - Zach Shackelford is a low end interior OL who will struggle to lock down a role as a guard — making him a center specific prospect who will need to work on his snap consistency and functional strength if he is going to latch onto a roster and potentially push for playing time. He's in need of more strength in the lower half and without much extension skills in the upper body, he's going to struggle to mask his lack of influence at the point of attack. Developmental player.
