In Pro Football Focus' grading system, Kaepernick sits right in front of Tennessee Titans quarterback Marcus Mariota.
Kaepernick finished last season as the 37th ranked quarterback in the NFL per Pro Football Focus, earning a 42.9 grade – the lowest of his career. This season, he is just above that grade at 46.1.
"Kaepernick's continued inaccuracy plagued the offense throughout and the offensive line did him zero favors," wrote Wes Huber of Pro Football Focus in regards to Kaepernick's performance against the Tampa Bay Buccaneers on Sunday. "Kaepernick accumulated a mere 143 passing yards on 34 attempts, 41 yards coming on the first drive and 36 of those gained during garbage-time check downs. Kaepernick would complete only two of nine attempts for six yards when under pressure and only twice attempted throws of 20 yards or more – both incompletions."
