Mike Nolan coached the 49ers for three full seasons before he was fired after Week 7 in his fourth year at the helm.
On Monday morning, he was asked about the situation in Santa Clara and if he would make a change at head coach or general manager.
"It's sad that it's gone to where it is," Nolan said on 95.7 The Game. "They're beginning to look much like when I took the job over in 2005 ... and there really was not a lot of good personnel on the team.
"The difference though that is better and will continue to be better, they will be (in) a much better cap situation going forward than we ever were back then ... but the losing I should say is really killing them.
"The personnel is not as bad as they're playing and that's the thing that really gets under your skin as a coach because you're frustrated by what's going on ... the thing that I have thought most of the season when people were talking about changes as the losses started to mount up, was not to change it. Because I know Trent (Baalke) personally, and Trent does a good job with personnel and that's his primary job.
"But for a lot of strange reasons -- guys retiring, guys quitting a couple years ago, just a lot of weird things that occurred -- their roster has kind of fallen off a little bit, but it is still a much better roster than some of these other teams that are not winning."
After winning their Week 1 game against the Rams, the 49ers have lost a franchise-record 11 straight games.
Chip Kelly is under contract through 2019 and the team owes Jim Tomsula $7 million over the next two years combined.
Baalke's contract runs through 2018.
"It's about players first and I think they have the right guy in place to pick the players but unfortunately for Trent, I think the choice of Tomsula hurt him and currently right now with Chip Kelly it's not helping him either," Nolan added. "They do not have a bad roster.
"Obviously they need a quarterback. They could be a .500 team in my opinion if they get a quarterback as near as next year even ... they got a tough decision to make at the end."
