On Tuesday, the 49ers’ offense was able to work against the defense for the first time during the offseason program on the first day of the team’s voluntary minicamp.
And it didn't take quarterback Colin Kaepernick long to show off the mechanical changes he underwent this offseason.
Kaepernick spent 10 weeks at the beginning of the offseason in Arizona working on his mechanics with private quarterback coach Dennis Gile. He also spent about one day a week on the mental aspect of the game with two-time NFL MVP Kurt Warner.
The makeover of Kaepernick was so noticeable, tight end Vernon Davis wondered if his eyes were deceiving him.
“When I saw him yesterday, I didn’t even know that was Colin,” Davis said after the final day of the first week of the 49ers’ offseason program. “Seriously, he was working on his drop-back. ‘Who was that?’ You guys are in for a treat. He looks like a totally different guy.”
Kaepernick also made an impression on 49ers' new wideout Torrey Smith on Tuesday.
