Where Johnson's plays went: throw and catch spots, air yards and yards after the catch, read from the play-by-play
The play-by-play names the defender on breakups, interceptions and tackles, but not the man in coverage on every throw, so true times-targeted isn't in the text. Coverage plays is the closest stand-in; exact targets come from hand charting.
