Trevor Lawrence
It’s a little bit unfair to include Lawrence on this list because he revived his career. But the Clemson star arrived in the NFL with staggering levels of hype around him. He was the most exciting quarterback prospect since Andrew Luck but there was one massive problem.

The Urban Meyer circus threatened Lawrence’s career as he failed to impress in Jacksonville. He endured a miserable rookie year but it wasn’t entirely his fault. Doug Pedersen replaced Meyer for Lawrence’s sophomore season and they made the postseason (via NBC Sports).
