That should alert fantasy football owners. It's not like Kaepernick is Peyton Manning or Tom Brady, but he's more of a fantasy option than Alex Smith ever was or ever will be, and that will really ring true in Week 14.
Miami is ranked 27th against the pass this year. Kaepernick struggled a bit in Week 13 against the St. Louis Rams, but the Dolphins pass defense is much worse. When you look at what he did to the Chicago Bears in his first start three weeks ago, it's not hard to say that he will light up Miami.
Kaepernick is an intriguing fantasy play because he's still an unknown. Even when he's struggling, he can do something like this at any time:
Miami isn't ready to deal with him, or anyone on the 49ers for that matter. The Dolphins are still a top 10 run defense, though, so you can bet that they will stack the box and make the inexperienced signal-caller beat them through the air.
Starting Kaepernick wouldn't be wise most of the time, but he's a quality play on Sunday if you don't have a superstar No. 1 option. The Dolphins have lost four of their last five games, and the 49ers will return home with an edge after falling to St. Louis in Week 13.
Miami will do its best to make this a one-dimensional game, and it might work. If it does, that's even better for Kaepernick's owners. Even if Miami stacks the box, it still can't account for his arm and the scrambling ability that results from a few big throws down the field.
He's still learning, but Kaepernick is an exciting player. If he's on your current roster, Week 14 presents the best opportunity to play him, and you should take advantage of that.
