5. Tua Tagovailoa
Miami fans were very excited to see Tagovailoa play for their franchise. But they didn’t see him until later in his rookie season because Ryan Fitzpatrick started. Then, he displayed a lot of rookie nerves when he finally usurped the veteran. The Dolphins benched him twice because of his mistakes.

Tagovailoa faced a summer of rumors that the Dolphins wanted to trade him. However, he started his sophomore year as their undisputed first-choice QB. Things didn’t get any easier for the former Alabama star. After making a number of mistakes on opening day, he fractured his ribs the following week (via ESPN). There’s no doubting his potential but the NFL is passing him by.
