The 49ers haven't done much in free agency. When they assemble for the start of the offseason program next week, the roster will look a lot like it did at the end of last season, at least from a personnel perspective. The big difference, of course, is the staff coaching them. Here's a stab at a rough depth chart for the beginning of the offseason. The theme: A lot of bodies; not a lot of experience.
Italics: Player who was not on San Francisco's 2015 roster.
Offense:
Quarterback: Blaine Gabbert, Colin Kaepernick, Thad Lewis, Dylan Thompson
Notes: Gabbert replaced Kaepernick as the starter in 2015, fared better than Kaepernick in the starting role and, unlike Kaepernick, will begin the offseason program healthy.
