Best: Baltimore Ravens – Joe Flacco
Even though the Baltimore Ravens were really the reincarnation of the relocated Cleveland Browns, since the Browns were awarded a new franchise with the same name, we’re treating the Ravens as a separate franchise in and of its own.
Given that the Ravens haven’t really had an illustrious history at the quarterback position, it’s hard to give this designation to anyone other than Joe Flacco. Flacco is the only quarterback in team history to play in more than 53 games for the franchise, and no other quarterback in team history has come close to his total career touchdown passes, passing yards, and total wins as a starter.
Worst: Baltimore Ravens – Kyle Boller
Despite having one of the all-time great defenses, the Ravens of the early 2000s had a rotating list of starting quarterbacks that never lived up to the quality of the defense. In 2003, the Ravens drafted Kyle Boller with their first-round pick to finally get their franchise quarterback.
It wasn’t Boller. He played 5 seasons in Baltimore and managed to play a full season just once. He managed to throw for more than 2,000 yards only once and retired with a career passer rating of just 69.5.
