At 6-6 320lbs, Walker possesses a long frame with equally long arms. He provides an excellent blocking radius for the tackle position in the pass game. Walker is not an elite athlete, but he possesses a good first step in pass sets, with average to good lateral quickness. What he lacks in athleticism, he makes up for with length. He has a dense frame and shows that he can absorb powerful edge rushers without losing his base.

In the run game, he is solid, showing he can move well and leverage his dense frame well against defenders. His ability to block in the run game is where he can excel the earliest in his career in the NFL.

Overall, Walker must improve his bend and hand placement. He can be out-leveraged due to his lack of bend, and his hand placement can be inconsistent.
