OG Zion Johnson, Boston College

6’3” – 316 lbs.

Background:

Originally attended Davidson, where he started nineteen games over two seasons before transferring to Boston College. Started seven games at left guard for the Eagles in 2019, then started all eleven games at left tackle the following year. Used a fifth year of eligibility to return to the team this past season, sliding back inside to guard.

Positives:

Five-year starter with experience at both guard and tackle. Fires out low and with some explosiveness. Works hard to stick with blocks through the whistle; overall ability to sustain is good. Understands positioning well and works hard to wall off defenders with his frame. Shows active leg churn after engaging to generate push; does an excellent job of attacking the defender’s shoulder and sealing them inside to create stable rushing lanes. Functional strength and toughness are very good. Gets enough torque from his upper-body to sling defenders down and doesn’t pass up opportunities to finish opponents. Nice knee bend and a wide base in his sets; difficult to get around even when he’s caught off-guard by the initial move. Easily absorbs power in pass protection. Accurate hand placement and reset. Able to cover some ground and set up a pocket on rollouts.

Negatives:

A little bit older than some of the other top prospects in this year’s class. Probably won’t receive much consideration as a tackle despite his prior experience there. Some issues bending at the waist and falling off of blocks while trying to play outside his frame. Did some blocking on angles but wasn’t asked to pull often and can struggle to line up blocks at the second level. Will lower his head into contact at times when playing in space. Too many pass protection reps where he’s idling around the line; can be late to recognize opportunities to help. Would like to see him be a little bit more aggressive with his punch and keep his back straight more consistently.

Summary:

A tough, thick offensive lineman with plenty of experience and an excellent work rate, he understands positioning and does a nice job of sealing holes in the run game, keeping his legs driving to move defenders. Can occasionally struggle to reach opponents, leading to some balance issues, but has starting-caliber traits on the interior of an inline/power-based blocking scheme if he can play within his frame more consistently. Looks like he’ll probably end up coming off the board sometime on the first day.
