Former 49ers quarterback Alex Smith admitted he was "shocked" by the changeover he saw from the San Francisco organization these past couple months.
"I think for me, it's still just tough to believe all those guys are gone, all that turnover," Smith told the San Jose Mercury News, referencing the dismissal of Jim Harbaugh and the majority of his staff. "I wasn't there, so obviously it's hard for me to speculate on any of that. I was just kind of shocked.
"There were a lot of ball games that got won over the last few years but for whatever reason, they couldn't make it work. I don't know. I wish coach [Jim] Tomsula well. I wish him the best."
Smith, 30, was the No. 1 overall pick by the 49ers back in 2005.
The quarterback has a storied history with the team, having struggled to get his career on the right track and live up to the expectations that were set for him as a rookie.
It wasn't until Harbaugh arrived in 2011 that Smith had a career turnaround. He posted his most passing yards (3,144), as well as the highest passer rating (90.7), in what was his sixth year in the NFL.
The 49ers went 13-3 and made it to the NFC Championship.

Though Smith was on the offensive side, he is also familiar with the team's new head coach, Jim Tomsula, having started Tomsula's one game as interim head coach in Week 17 of 2010.
Smith beat the Cardinals 38-7, and finished 15-of-29 for 276 yards, two touchdowns and no interceptions. His 107.8 rating in that game was his second highest of that season.
"I loved what [Tomsula] brought to the team that week," said Smith. "I know he has the ability to be a head coach. He's a good man, a really good coach. I'm pulling for him."
