The San Francisco 49ers have plenty of salary cap space. They have 12 picks in the 2016 NFL draft. The roster is young and was relatively poor in 2015. All of those factors contribute to the reality that 2016 is not a “reload” for the 49ers. They are knee-deep in a rebuild. Besides perhaps 10-15 players, this roster is unsettled and could see changes among starters at most positions.
The positional group that has seen the most change, and realistically should see more by the time the 2016 season begins, is the offensive line.
The development from the beginning of the 2015 season to the end was encouraging, spurred by the demotion of starting right guard Jordan Devey.
