San Francisco 49ers tight end Vernon Davis likes the new look quarterback Colin Kaepernick is showing this offseason.

Kaepernick spent the past two months working on his mechanics in Phoenix with the likes of quarterback coach Dennis Gile and two-time league MVP Kurt Warner.

“I didn’t even know that was Colin,” Davis said to reporters Friday at Levi’s Stadium as the 49ers began their offseason program. “No, seriously. He was working on his dropback and I was just, ‘Who is that?’

“You guys are in for a treat. He looks like a totally different guy. I think it was really genuine and I think he’s just a class guy. It shows that he’s humble, for him to go to someone and work on his craft and get better. And it shows that his approach to this game, he’s just relentless.

“He just wants to be great and I respect that. And that’s another reason why I’m in this building today.”

Kaepernick talked to reporters about changing five years into his NFL career.

“I just want to make sure I’m doing everything I can to make sure I’m getting better and doing my part to help this team win,” he said. “You have to be able to change and adapt to be the best player you can be.”

Kaepernick passed for a career-high 3,369 yards last season when the 49ers missed the playoffs, but his total quarterback rating dropped. He had 19 touchdown passes and 10 interceptions in 2014.

Kaepernick was asked why he feels the need to alter his offseason approach.

“To get better,” he said. “We didn’t have the season we wanted to last year. I could have played better last year. Offensively, we should have played better last year. So, something had to change.”

New head coach Jim Tomsula has yet to see the new and improved Kaepernick throwing the ball. Rules probit coaches from interacting with players on the field during this phase of the offseason program.

“Colin Kaepernick was not broke,” Tomsula said. “None of us had a good season last year, OK? And we’re not going to spend a lot of time talking about last year, OK? We’ve got one of the most prolific quarterbacks in the National Football League sitting next to me, all right? This is a guy that went out and busted his tail. He took good and made it better.”
