The 49ers stand to get younger this offseason as they part with backup quarterbacks Jamie Martin and J.T. O'Sullivan.
Both are scheduled to become unrestricted free agents. Neither is expected to return.
The chart ranks the 49ers' scheduled unrestricted free agents from oldest to youngest, with ages rounded down to the tenth.
Only three of the 49ers' scheduld free agents are in their 30s, easily the lowest figure in the division. The Cardinals (nine), Rams (eight) and Seahawks (eight) each rank among the NFL's top five teams in 30-plus UFA candidates.
None of the 49ers' scheduled free agents appears to be critical for the team's future. Re-signing Takeo Spikes would make sense. Most of the others appear to qualify for the dreaded at-the-right-price distinction, meaning the 49ers will probably take their time in re-signing them, if they re-sign them at all.
