Ranking every San Francisco 49ers quarterback since 1980
Here we rank the all the San Francisco 49ers starting quarterbacks from 1980 to the present day.
13. J.T. O'Sullivan (2008)
J.T. O'Sullivan had a very short, and equally unsuccessful tenure with the 49ers.
He won the starting job to begin 2008, as Alex Smith was as out with a shoulder injury all season. However, after winding up with a 2-6 record, the team opted to return to Shaun Hill as a starter.
2008 would be O'Sullivan's one and only season with the team.
