A quick observation of quarterback Colin Kaepernick and how he played in the San Francisco 49ers' 19-3 loss to the Seattle Seahawks in Week 13:

Remember when Kaepernick was the most dynamic running quarterback in the league, or at least, one of the most dynamic?

Yeah, he does, too.

“A lot of it,” he said after the Niners’ Thanksgiving loss, “is just opportunity.”

Kaepernick appears hampered by the team’s intentions to turn him more into a pure pocket passer. Which is why he was asked after running the ball just three times, for 17 yards, against the Seahawks if he would like to open up that part of his game more.

“Anything we can do to help us win,” he said.

The 49ers, who are 7-5 and most likely need to win their final four games plus get some help to make the playoffs, probably need to unleash Kaepernick’s rushing game and designed runs to keep defenses honest.

And it likely gives the Niners their best shot at offensive success.

“Everything we need is in the building,” Kaepernick said. “We have great players across our offense. We have to go out and play like it.”

Starting, perhaps, with a zone-read option ... or 10.
