The 30-year-old quarterback said he's closed the book on his 49ers days and has no unfinished business in San Francisco.
"I did feel like it was complete," he told Bay Area media on Wednesday, per the San Jose Mercury News. "I felt like we had rebounded, even if it took a lot longer than I ever thought. We got the organization back to where it needed to be and better than when I came in. So, yeah, I didn't have any regrets when I left."
Smith said he doesn't harbor any bitter feelings toward the organization that drafted him and then traded him away as he hit his stride. Smith did add that he hasn't talked to Harbaugh in a while.
The signal-caller has been fascinating to watch in Kansas City this season. Despite a poor offensive line, Smith has made plays and been a scrambling maniac. He's been one of the most under-the-radar, entertaining quarterbacks through the quarter-pole.
