After 11 straight losses and another lost season, 49ers ownership is open to significant changes just one year into its latest coaching/management regime, league sources said, with longtime general manager Trent Baalke in jeopardy of losing his job and coach Chip Kelly hanging in the balance as well.

It would be a surprise if Baalke was retained, though he has deep ties to owner Jed York and has been viewed as a loyal and trusted employee. The 49ers' roster has fallen into decay after years of suspect drafts and free-agent decisions, and the franchise is under intense fan pressure to make some changes.

Several NFL owners believe Jed York's parents, Denise and John York, will be taking a more hands-on approach with the team as they determine how to reposition the franchise, and Mike Shanahan, who has been under consideration for coaching openings there in the past, could join the 49ers in a coaching and/or executive capacity. His name continues to be connected to potential openings there, and the Yorks have spoken to him in the past.

While there have been recent reports that Kelly, in his first year as 49ers coach with just one victory thus far, is safe, sources say that a final determination on that matter would not occur until after the team has sorted out its front office.

Kelly has already matched the loss total of former coach Jim Tomsula, who lasted just one season at the helm after replacing Jim Harbaugh. The heavy-handed manner in which York handled Harbaugh's departure continues to haunt the franchise. The 49ers are 7-26 dating back to Thanksgiving 2014 (.212 winning percentage), with only the Browns owning a worse record in that span.
