Alternate headline: "49ers Bench Kaepernick For Worst Quarterback Of The DVOA Era."
Look, things in San Francisco are clearly going badly. Colin Kaepernick is last among starting quarterbacks in passing DYAR, and only Ryan Mallett is worse by DVOA. (And given that Mallett is currently unemployed, he probably won't qualify for these tables in a few weeks.) So it's understandable that the 49ers would consider a quarterback switch.
Or at least, it would be, if the alternative wasn't this guy:
|Worst Passing DYAR, 1989-2014|
|Blaine Gabbert||2011-14||JAC, SF||-1,685|
|Ryan Leaf||1998-01||SD, DAL||-1,388|
|David Carr||2002-12||HOU, CAR, NYG, SF||-1,328|
|Rick Mirer||1993-03||SEA, CHI, NYJ, SF, OAK||-1,242|
|Trent Dilfer||1994-07||TB, BAL, SEA, CLE, SF||-1,191|
|Josh McCown*||2002-14||ARI, DET, OAK, CAR, CHI, TB||-1,172|
|John Skelton||2010-23||ARI, TEN, SF||-997|
|* This does not inclues McCown's 144 DYAR and counting with the Browns
this year. If McCown finishes with at least 203 DYAR this year, he will
fall out of the top 10 and Chad Hutchinson will take his place.
