Updated through Week 14

Over halfway through the 2017 season, Colin Kaepernick is still unemployed – and still the topic of contentious debate. And even with injuries piling up for NFL starting quarterbacks, a signing looks nowhere in sight. On Oct. 15 it was announced he would file a grievance against the NFL's owners for collusion in keeping him out of the league.

Here's how the 2016 performance of the former San Francisco 49ers quarterback compares to the 2017 performance of each team’s most recent starter, using a stat called adjusted net yards per attempt.

Among starting quarterbacks, 13 are worse than Kaepernick, 4 are about the same (plus or minus 0.35 ANY/A) and 15 are better.

ANY/A is a tweak on yards per attempt that gives QBs credit for throwing touchdowns and penalizes them for interceptions and sacks. It’s calculated as: (yards + 20 * TD - 45 * interceptions - sack yards) / (attempts + sacks).

Having a capable starter under center in the NFL is a requirement for success, and adjusted net yards per attempt is one of the best measurements available for QB passing performance. It correlates more closely with winning than either traditional passer rating or yards per attempt.

ANY/A is a tweak on yards per attempt that gives QBs credit for throwing touchdowns and penalizes them for interceptions and sacks.

Note that ANY/A only measures passing. Quarterbacks who run a lot – such as Kaepernick, Cam Newton, Russell Wilson and Marcus Mariota – are not given credit for those contributions. Here’s the full starting QB ranking, from worst to best:
