Boomer Esiason – 1988
The Bengals went 4-11 in 1987 and nobody expected them to show much improvement the following season. But Esiason inspired them to a brilliant regular season and they improved to a 12-4 record. His consistent performances were enough to merit an MVP win. This was also the second time a Bengals player won the coveted award.

It was a close-run thing because Randall Cunningham narrowly lost out. Meanwhile, it was vindication for Esiason who had a turbulent relationship with fans the previous years. Many of them wanted him to lose his place as the starting quarterback. But he rebounded in style as he proved himself in front of the world (via Stat Muse).
