The Kansas City Chiefs signed quarterback Matt Cassel to a six-year, $63 million contract, which also includes $28 million in guaranteed money. Cassel will receive $40.5 million in the first three years of the deal.

Had the Chiefs not signed Cassel to an extension, they would have owned him $14.65 million this season, because he signed a franchise tender with the New England Patriots earlier this offseason. When Kansas City traded for Cassel a few months ago, they assumed his contract.

The 27-year-old Cassel will have the opportunity to work with offensive-minded Todd Haley, who did wonders last year in Arizona and now is the Chiefs’ new head coach. If Cassel can continue to improve in his second full season as a starter, Kansas City has enough offensive firepower to be dangerous, although the offensive line will probably have to over perform.

Either way, Cassel has a lot to live up to. His contract makes him one of the highest paid quarterbacks in the league and ironically, he now makes more than Tom Brady. If he eventually makes the Chiefs a winner, nobody will question his lofty contract figures. But if he fizzles, Cassel’s contract could haunt KC for years to come.

Oddsmakers from online sports book Sports Interaction have made the Chiefs 65/1 long shots to win the 2010 Super Bowl. KC is also 35/1 to win the AFC.
