Spin it how you want but this is fact. Per espn:
" Speaking of "What have you done for me lately?" recency bias brings us to San Francisco, where in just 21 months, Colin Kaepernick went from being one pass away from back-to-back Super Bowl trips as recently as January 2014 all the way to benched for Blaine Gabbert. And then Gabbert outplayed him. You can spin a narrative where Kaepernick emerged with a great running game, a dominant defense and an incredible head coach running an unfamiliar zone-read scheme in 2012 and then slowly saw his talents fade like he was living out a football "Flowers for Algernon."
Again, though, you can't just write off the past as totally irrelevant. The idea that teams somehow discovered Kaepernick's fatal flaws on film like he was a pitcher tipping his curveball is absurd and doesn't match up with how defenses actually attack quarterbacks. If Kaepernick was a ticking time bomb waiting to be found out by a smart enough coach, he wouldn't have flummoxed Belichick in December of 2012, or nearly beaten the Ravens when they had two weeks to break him down before the Super Bowl, or stomped on the Packers after an entire offseason of tape in Week 1 of 2013.
Defenses did grow more comfortable in attacking the read-option, and it's unlikely that Kaepernick will ever again run roughshod over a defense like he did when he annihilated the Packers in the 2012 playoffs, but the Chiefs, Seahawks and Panthers all manage to incorporate the zone-read into their offenses right now, and they're doing just fine.
.... It's also bizarre to suggest that Kaepernick was unplayable in 2014. He did take a step backward from where he had been in the previous two years, but he was a totally justifiable choice at quarterback. He finished 15th in Total QBR, which includes his considerable value as a runner, with a figure of 60.0. That mark wasn't subject to a second-half decline, either; Kaepernick was actually 11th in Total QBR (at 62.2) over the final eight weeks of the year."
