He's only been in the top 10 in completion percentage once in his career and that was last year (when McCaffrey arrived- no coincidence). The previous four years combined he was just 57.5%. But his ability/threat to run (2,300 yards over those same four years) made up for it. That part of his game is leaving him and making him become exposed as a mediocre at best pocket passer. Maybe not even mediocre.
