Strengths
The combination of his height, long arms and athletic build makes him a great candidate for playing on the outside of an offensive line. Due to his length and good depth of his kick-step, he can re-route defensive ends around the outside of the pocket. He also has the ability to stop them in their tracks if they attempt to take an inside lane.
Williams has a very strong upper body and big hands that allow him to grasp a defender and control him throughout the duration of a play. He is a very smart player who understands the nuances of rushing angles and uses his knowledge to defend them properly.
He comes off the ball hard and is able to get to the second level on rushing plays and sustain blocks that can spring a running back into the open field.
Weaknesses
Williams is still a bit raw at the offensive tackle position having only played for a season-and-a-half on the right side of the line. He misses certain subtleties of the game due to this. He has been caught turning his head toward his target, and that can tip off a defense as to the direction of the play.
He does not have elite quickness at the tackle position, which can hurt him in run-blocking and also limit him to the right side of the line.
His ability to lock on to faster defensive ends needs to improve. Williams will allow his hands to slip outside the numbers when he is beaten off the line, causing holding penalties.
