Joe Montana – 1990
Nobody knew that they’d only see Montana play once for the Niners again after 1990. He won his second consecutive MVP award as he performed at the peak of his powers. They went all of the way to the NFC Championship but didn’t win that game. However, Montana was excellent throughout the regular season.

He set career bests across some metrics but fans will never forget this because it was his last year as San Francisco’s starter. Montana injured himself in the 1991 preseason and missed the entire year. Then the 49ers opted to replace him with Steve Young after he made a single appearance in 1992 (via Yardbreaker).
