Turmoil might undersell what went on with the San Francisco 49ers this offseason. They said goodbye to Jim Harbaugh and Frank Gore, and nearly their entire linebacking corps decided to hand in their retirement papers.
Sure, the team gave quarterback Colin Kaepernick a desperately needed deep threat in Torrey Smith and got value contracts from veterans Reggie Bush and Darnell Dockett, but "disappointing" is probably the nicest term most 49ers fans would use to describe the last few months.
All of which makes the 2015 team one of the most interesting in football. Jim Tomsula will have to prove himself as a viable head coach.
