24. Cody Pickett
“Your QBs may be bad,” one long-suffering Niners fan said. “But they’ll never be Cody Pickett going 1-13 for 28 yards and an interception bad.” In sum, Pickett was horrendous. He only started two games in his two seasons with the San Francisco 49ers but he forced everybody to sit and suffer. The game that this fan referred to was against the Chicago Bears in 2005.

It was the second of his two starts for the Niners that was the clear worst of the bunch. Pickett threw two incomplete passes in the first half and was almost equally ineffective in the second. But he almost scored a touchdown before running into Chicago linebacker Brian Urlacher. He is definitely one of the most dreadful historic quarterbacks as he made mistake after mistake.
