16. Worst-Ever?
“I just had a flashback of Troy Smith against the Packers,” one Niners fan shudders. “Gotta take my break from work now.” This was an appropriate response because Smith was one of the worst quarterbacks the NFL has ever seen. Even the best signal-callers make mistakes, but in this case, he was the mistake. The Packers defeated San Francisco 34-16 in that game while Smith was appalling.

Smith started six games for San Francisco before the Niners replaced him with Alex Smith. He did have some good moments in red and gold, but the reality was that he lacked the consistency to make it as an NFL starter. Finally, he left the league for the CFL where he finished out his football career with the Montreal Alouettes. It just goes to show that not every Heisman Trophy winner will become a historic legend.
