Matthew Stafford
Stafford spent a decade in the wilderness with the Detroit Lions before he joined the Rams. He had an up-and-down career in the Motor City with some great performances but occasional declines in form. However, the overall consensus was that he was one of the most underrated NFL quarterbacks (via CBS Sports).

Sean McVay agreed and decided that he was the man to get the Rams over the line in their Super Bowl quest. McVay and the Rams soon sent former Super Bowl starter Jared Goff and multiple first-round draft picks to Detroit for Stafford. The move worked perfectly and Stafford departed to win his first ring. Most Detroit fans gave Stafford their blessings when he left the franchise. But there’s no denying that he broke some hearts because they wanted him to stay.
