Rich Gannon
Many people don’t give Gannon the credit that he deserves. The quarterback was brilliant for the Raiders during their Super Bowl run in 2002. Yes, he had a meltdown in the showpiece event but he still had a great season. Furthermore, his absence was conspicuous throughout 2003.

That’s because Gannon’s shoulder injury seriously impacted their playoff dream. They finished with a miserable 4-12 record after his problems. There’s a good chance they would have missed out anyway but this was a bridge too far for the franchise (via USA Today Sports).
