4. Sam Howell, Washington Commanders
It was pretty obvious that Howell was going to come in last on this list. He started just one game in his rookie season and hasn't proved anything yet to be higher on this ranking.
Howell sat behind Taylor Heinicke and Carson Wentz in 2022 before earning a start in Week 18 against the Cowboys. The rookie showed some potential in that game by throwing for 169 yards on 11-of-19 through the air with one touchdown and one interception.
Still, no one has any idea how Howell will turn out. He'll likely head into camp as the QB1, but that could quickly change if he struggles early. Veteran Jacoby Brissett -- who did a nice job with the Browns last season-- could take over at any point.
Howell has the college track record to help the Commanders win some games in 2023. He threw for over 3,000 yards in all three of his college seasons while throwing 38 pass touchdowns as a freshman at North Carolina.
Howell will surely be given the keys to Washington's offense this season before making a possible quarterback change next season. If the Commanders struggle to win games, USC phenom Caleb Williams could be a target for them in the 2024 NFL Draft.
