‘The Bills bulked up with big personnel groupings on 68% of the offensive snaps in the win over San Francisco. It made perfect sense, given the snowy field conditions. The Bills used extra offensive lineman Alec Anderson as a jumbo tight end in a three-receiver formation with no traditional tight end on the field (10-plus personnel) on 10 plays. It worked. James Cook’s 65-yard touchdown run came out of that grouping. Offensive coordinator Joe Brady had run 10-plus personnel only three plays in the first 11 games of the season.’
