His seasons as a head coach from 2004 on, from ESPN’s play by play: fourth downs where he went for it out of every fourth-down decision; how often he went when SportsDataverse’s fourth-down model said going for it was the better call; the share of his offense’s plays that were passes; seconds of game clock per offensive play (lower is faster); and expected points added per offensive play (EPA, a measure of how much each play moved the offense toward points). The season in progress counts its games so far. SportsDataverse’s coach tendencies, from ESPN’s play by play; the EPA and the fourth-down model are SportsDataverse’s.
