The Facts: Kaepernick’s 10-week offseason session in Arizona is over, and the man who worked most closely with him believes the time spent was beneficial for all involved. Kaepernick logged five days a week, beginning Jan. 12, working out, watching film and fine-tuning his mechanics with quarterback coaches Dennis Gile and Mike Giavondo. Two-time NFL MVP Kurt Warner spent time with Kaepernick for approximately 10 sessions during that time. “I don’t think there was a throw he couldn’t make when he first got here,” Gile said on Sunday. “I just think the consistency and efficiency of it was what we wanted to get better at, and I think that’s where we made tremendous strides. He became a lot more consistent and efficient with those balls.”

Diehards Line:Kaepernick completed 60.5 percent of his pass attempts last year in his second full season as the 49ers starter. He threw for a career-best 3,369 yards with 19 touchdowns and 10 interceptions. But his passer rating dropped to a career-low 86.4 and the 49ers finished out of the playoffs with an 8-8 record. His arm strength and ability to drive the ball down the field has never been in question, but Kaepernick’s accuracy and touch on the shorter throws has been seen as an area in which he can improve. GM Trent Baalke suggested last month Kaepernick would set out to hone his “footwork, delivery, changing platforms, throwing platforms, arm angle,” as well as adjusting the velocity on his shorter throws. The short-passing game figures to be more of an emphasis this season with the addition of free-agent running back Reggie Bush, who has averaged more than 50 receptions per season in his nine-year NFL career.
