SAN FRANCISCO — Former NFL star quarterback Kurt Warner worked with the 49ers’ Colin Kaepernick for several weeks last off-season trying to sharpen some of his technical issues. Evidence of Warner’s tutelage didn’t show up much during the season, however, and now Kaepernick’s career may be at a crossroads both with the 49ers and in the league.

Warner hopes the 49ers give Kaepernick another chance, however, because he believes all struggling NFL teams are spinning their wheels going from young quarterback to young quarterback, particularly those that weren’t groomed as drop-back passers. He also thinks the hiring Chip Kelly might be the perfect antidote to at least some of Kaepernick’s on-field problems.

“The thing you have to realize with guys like Colin, Robert Griffin III and Johnny Manziel is the way they were asked to play before they got to the NFL was just ‘be an athlete, see what you see and then create,'” Warner said Tuesday at Moscone Center, where he is part of the NFL Network studio team. “So I think a transition like this to a Chip Kelly is going to ask Colin to do a lot more of that while he also learns how to play the position better. That to me is what it’s all about.”

The question may be whether Kaepernick wants another chance with the 49ers. The New York Daily News reported Tuesday that Kaepernick is disillusioned with the franchise, wants out, and hopes to land with the New York Jets.

Kaepernick still has five years remaining on a $114 million contract but the club has several outs, including this off-season. The 49ers have until April 1 to decide whether to trade or cut the quarterback or pick up his 2016 base salary of $11.9 million.

Warner believes NFL teams have to start showing a lot more patience with their young quarterbacks, particularly those who ran spread or read-option offenses in college, and said Kaepernick is a classic example.

“It’s hard enough for those of us who were drop-back quarterbacks all of our lives to play at this level,” he said. “For guys who have never really been taught that, it’s almost impossible for them to do it. So what I like about the (Kelly) fit is it’s going to give him the chance to do the things he does well and hopefully, in the process, he can continue to learn how to play inside the pocket, reading coverages and winning that way as well. But it’s going to take some time.

“When Colin was forced to do it the other way, we saw that he still had some growth to make,” Warner continued. “He wasn’t given a great opportunity to grow because we’re in that business where it’s not for long. If you don’t do it now, we’re going somewhere else. So I’m hoping this buys him some time to, a) get back to having some success doing what he does well and, b) grow into what everyone hopes he can be 4-5 years from now.”

Warner also said to expect miracles from the work he did with Kaepernick in the offseason was unrealistic.

“I can work with him 6-8 weeks in an off-season, but that still doesn’t teach you how to play the game,” he said. “You don’t have the speed of the game, you don’t have to read different guys and see different scenarios. You can work on technique things, but none of it means anything if you can’t take it and apply it on the field and have opportunities to learn it on the field. You’re going to make small strides in certain areas, but then you have to learn a lot more on the fly.”
