The 49ers rolled over $56 million in unused cap space from last season and will enter free agency next week with plenty of flexibility to get things done. “We’re extremely well-equipped to do what we wish,” 49ers general manager John Lynch said last week at the NFL Scouting Combine in Indianapolis. The league-wide salary cap was set on Monday at $177.2 million per team. With the cap rollover from last season, the 49ers have a salary cap of $233,248,430 for the 2018 season, according to the NFL Players Association. Lynch said the 49ers will have cap space in the mid-$50-million range when factoring in all upcoming expenditures, including players on injured reserve, the estimated rookie salary pool and the space required for the 10-player practice squad for the regular season.
