Tbh I think humph is the worst matchup for Williams, especially considering Williams has already completely demolished Humphrey before on colleges biggest stage, because Williams is one of the best jumpball artists in the league and Humphrey severely lacks the ability to go up for the ball with a highpointing receiver. He’s done incredibly well breaking up a pass last second, but Williams will force him to turn around and play with his back to him, and Humphrey has not shown he can do that.
add to that just how physical jimmy smith is and how much jimmy enjoys confrontation with receivers and i think that's probably a better matchup
