SANTA CLARA, CA — Still steaming over the Super Bowl loss, Colin Kaepernick packed up his belongings in the 49ers locker room and made plans with teammates to work out this offseason.

They won’t have to wait long.

Kaepernick said Tuesday that he’ll be training in Atlanta within a week, and the strong-armed and fleet-footed quarterback will be bringing some of his receivers along with him. All of it is part of Kaepernick’s quick evolution from backup to starter that will continue as he enters training camp as the unquestioned franchise star.
