Colin Kaepernick's confidence soaring in camp with more experience running 49ers offense

Just a week into training camp, Colin Kaepernick can already feel the difference between where the San Francisco 49ers offense is now versus this time a year ago.

All of his teammates can see the evolution, too.

Kaepernick's confidence and comfort level has been soaring on and off the field. He has been tossing deep balls with more touch behind that powerful right arm — even leaving All-Pro linebackers questioning how to defend such precision — and strutting around the 49ers facility with a black beanie on his head and bright red head phones around his neck to show off his swagger.

The biggest challenge for Kaepernick so far in training camp has been finding rhythm with all of his receivers. That has been increasingly difficult because of injuries.
