Jared Goff
Everyone had massive expectations for Goff in Los Angeles. The Rams made him the first overall pick in 2016 and they immediately red-shirted it. But he became the starter toward the end of the season and held this position for two years. Goff made back-to-back Pro Bowl appearances and played in a Super Bowl.

But he never convinced Sean McVay that he was the man despite the hype. Goff’s confidence went down after the Super Bowl defeat and his form deteriorated. In the end, they sent him to Detroit where he underwent a remarkable career revival (via The Ringer).
