There may not be a more polarizing figure in Kansas City history than current quarterback Matt Cassel.
Cassel has only had one productive season for the Chiefs, and many fans are looking for the front office to find a long-term replacement for the USC product.
To be fair, Cassel has not had much help during his tenure at Arrowhead Stadium. Cassel has endured a lockout, a host of offensive coordinators and a rash of injuries while he has been under center. He also endured a season-ending thumb injury during Week 9 last season as well.
When all the elements were in place in 2010, Cassel had his best season as a Chief. Cassel threw for 27 touchdowns and only seven interceptions, while Kansas City won the AFC West.
Cassel is a victim of the dismal quarterback history that has plagued the franchise for the better part of the last 20 seasons. The front office has failed to address the quarterback position long term, and this has been the main reason that the Chiefs have not won a playoff game in two decades.
This has caused the ire of many fans that are desperate for a playoff victory.
Right or wrong, the only way for Cassel to get all of the fans in Kansas City firmly behind him is to make a run deep into the playoffs.
He makes this list because this is likely the last season where his stock can be considered uncertain, and 2012 is truly a boom or bust year for Cassel.
