The Facts: Rosen's latest landing spot will be his home for the next year. San Francisco has signed Rosen to a one-year contract, the team announced Monday. The team also signed running back Austin Walter, which it announced with the same press release.

Diehards Line: Rosen was part of the Buccaneers' practice squad when San Francisco found itself in need of quarterback depth late in the season. The 49ers signed Rosen off the Buccaneers' practice squad on Dec. 23, and he spent the rest of the 2020 season with San Francisco. General manager John Lynch apparently sees enough in the former No. 10 overall pick of the Cardinals, keeping him around for another year as part of a team that has needed its depth at the position more often than most clubs due to Jimmy Garoppolo's various injuries. With little pressure on him to produce in San Francisco, Rosen might finally be in an ideal situation to learn the pro game under offensive wizard Kyle Shanahan. He'll get at least one more year to soak up as much as possible with the 49ers.
