The San Francisco 49ers have won four of the five games Colin Kaepernick has started, but that success hasn't translated to increased production from tight end Vernon Davis.

After catching six passes for 83 yards in Kaepernick's first start, Davis has just four catches for 29 yards in the last four games combined. Davis said part of the limited production is a lack of developed chemistry between he and Kaepernick. Davis said it takes time to develop a bond between a quarterback and receiver and right now he and Kaepernick are not always on the same page.

"We don't have that timing, but it will come, just like any quarterback and wide receiver. It takes time," Davis said, according to SFGate.com.

Kaepernick overthrew Davis twice against New England and Davis said the second-year quarterback is still adjusting to his speed. Davis also said it takes longer to get on the same page depending on the routes as speed and other factors come into play on deep routes. While he expects it to take time to develop, Davis said he thinks the relationship will grow quickly.

"With Kap I'm sure if just continue to rehearse and work on it, we can make it happen. He's a fast learner, just like Alex. But it takes time," Davis said.
