11. Matt Cassel
No matter where I put Cassel on this list, there was going to be some serious debate. Some will argue that this is too high for Cassel, who came in with massive expectations after a good season as Tom Brady’s backup in New England. Others will say this is too low because Cassel was forced to play with a bag of trash outside of the immortal Jamaal Charles.
For me, Cassel falls somewhere in the middle. He was not the worst quarterback the Chiefs have ever had, but he was very limited. Cassel was fairly mobile but had a weak arm and locked onto his first read. If the primary target was covered, Cassel would hold the ball and take a sack more often than not.
So why does he even get this high? Because he played behind one of the worst offensive lines I have ever seen and somehow made the Pro Bowl in 2010, albeit as an alternate. Cassel threw 27 touchdowns that season under offensive coordinator Charlie Weis, helping Kansas City to a 10-6 record and an AFC West title.
However, it was all downhill from there. Cassel was mediocre in 2011 before enduring a season-ending injury and then lost his job to Brady Quinn in 2012. Cassel was also at the center of an embarrassing moment for Chiefs fans that year, sustained a concussion at Arrowhead Stadium to the cheers of fans.
