Walker began his college career at Coffeyville Community College in Kansas. After earning JuCo All American honors, he moved on to the Sooners and had immediate success on the field for them as well. He took over the starting role at right guard as a sophomore and held the job for the remainder of his career.
Strengths
Walker is an underrated lineman that has a nice overall game. He is quick off the snap and to set up in his stance. He has solid athleticism and shows the ability to slide well laterally and does a good job in pass protection. Walker also shows some mobility to get out and block in space and pick up defenders on the move. He also shows some power at the point of attack and can drive defenders off the line of scrimmage to create a running lane for his running back.
Weaknesses
Walker does not always play with the same intensity level. He lacks the aggressiveness and killer instinct to maintain his focus and finish off blocks. He appears to rely on his natural gifts too often and must learn to play with a sense of urgency on the field.
Future
Williams may be the most unheralded of the Oklahoma offensive lineman but he has the physical tools that project well to the NFL. He may need someone to push him to reach his potential, but the ability is there in the middle of day two to be a surprise for the team that takes the chance on him.
