ESPN's Bill Barnwell recently ranked this season's San Francisco 49ers as the second-most unlikely Super Bowl team of all-time — a list of the most surprising squads to earn a trip to sports' biggest stage.

ESPN insider Field Yates believes a win in Super Bowl LIV would push the 49ers into the No. 1 spot as the most surprising NFL champion of all time, and it's not only because the team managed just four wins a season ago.

"They win the Super Bowl, greatest ever," Yates responded on NFL Live when asked where this 49ers squad ranks among the teams with great one-year turnarounds. "And I know the question is one-year turnaround, and last year, they were 4-12 — they picked two in the draft — but do you know what they did the three years prior to last year's 4-12? They lost 10-or-more games.

"First team ever to go from four straight 10-or-more-loss seasons to the Super Bowl. They have an opportunity to finish the job. If they do so, I think it's the greatest turnaround in the history of the NFL from one season to the next."
