I think this award is given by the Augusta Sports Council so this is a pretty blatant snub.
"The Ray Guy Award winner is selected by a voting body of Football Bowl Subdivision (FBS) sports information directors, national media and former Ray Guy Award winners. Punters are evaluated on their overall statistics and contribution to the team. Particular emphasis is placed on the following statistics; net average, percentage of total punts inside the 20-yard line and percentage of punts not returned."
Pretty obvious the voters purposefully skipped over him.
But nothing you can do about it,.
