3. Kyle Boller
Those years between the 2000 Super Bowl team and McNair were spent trying to find answers at quarterback, and Baltimore thought they had it figured out when they drafted California prospect Kyle Boller with the 19th pick in the first round back in 2003.
Boller came out as one of the top passers in his draft class, alongside guys like Carson Palmer, Byron Leftwich and Rex Grossman.
He would go on to start 42 games for Baltimore and owned a career record of just 20-22. However, once again we have to revisit the fact that the Ravens are still one of the youngest franchise in NFL history, and it doesn't take much to make their all-time leaderboards.
Boller is third in Ravens history with 7,846 passing cards. He threw 45 touchdowns to 44 interceptions, and no stat better represents his time with Baltimore than those two. He was, by the very definition, a mediocre quarterback. As a former first-round pick, Boller could absolutely be labeled a bust. Although, he did see his career last from 2003 all the way to 2011, having also played for the Rams and Raiders before calling it quits.
