Scout ranks Polley as the No. 8 offensive guard in the state of Texas and No. 55 nationally at his position, but he could also potentially play tackle in college. Polley also has a chance to be a late-cycle rankings riser following a strong senior season.
Grant Polley is a potentially position-versatile offensive linemen who thrives in the run game and plays through the whistle. Plays left tackle for his high school squad and could possibly play outside in college, or move inside to a guard position. Light on his feet, especially running straight line to block at the second level.
High-intensity, high-motor player who doesn't stop blocking until he's put his opponent on the ground. Good lateral mobility for an offensive lineman, which helps him in pulling situations. Can improve technical aspects of line play, including leverage consistency and use of hands.
Spring of his junior year was huge for his recruitment with numerous P5 offers. Polley is a quality offensive line prospect who could fill one of multiple roles for a high-major program. - Gabe Brooks
Game evaluation from September
Polley is a long-armed player who though we project as a guard, could wind up being a position-versatile player in college. He has adequate high for just about anywhere on the line and his wingspan is noticeable even from the press box. Polley measured 6-foot-4, 263 pounds in the spring, but looked larger. Sure enough, he said after the game that he was up to 285 pounds.
Polley can be a road-grader in the run game. There are technical aspects that will be addressed once he's in college -- hand placement, leverage consistency, etc. -- but his physical nature and high motor make him a difficult matchup for smaller defensive ends. He really leans on those guys and his ability to consistently win that matchup makes him quite a commodity for Denton High, especially late in games when they want to run the ball.
But his greatest attribute is likely his aforementioned potential for position-versatility. I would think that has much to do with his lengthy offer list. In Polley and William Sherman, Colorado has commitments from two of the top six offensive guards in Texas' senior class, which is strong at the top of the guard group. - Gabe Brooks
