John Clayton wrote a recent column over at ESPN recently detailing the 10 worst contracts in the NFL. The Chiefs hold two of those. Both Matt Cassel and Tyson Jackson made the list, and it's a testament to just how poorly things have worked out for Cassel and how much Jackson's deal needs restructuring.

Clayton says that Cassel's contract likely means he's finished in KC after the 2012 season:

A good portion of the Kansas City crowd cheered when Cassel suffered a concussion. Cassel has recovered, but he has lost his job to Brady Quinn. This is Cassel's fourth and, most likely, last season in Kansas City. His salaries go to $7.5 million and $9 million in the final two years of his contract, but he's never completed better than 59.5 percent of his passes for better than 6.9 yards an attempt.

As for Tyson Jackson, the Chiefs defensive end appears at No. 7 on the list. Clayton writes:

Scott Pioli drafted Jackson with the third pick of the 2009 draft to be a mainstay in the Chiefs' 3-4 defense. The problem is that Jackson and Glenn Dorsey come off the field when opponents go to three- and four-receiver sets. In only one game this season has Jackson been on the field for more than 40 plays. He has two sacks and 139 tackles in four seasons and his salary goes to $14.72 million next year, the final year of his contract.

While one player will likely walk, it will be interesting to see if the Chiefs restructure Jackson at some point in the near future. It's hard to imagine the team eating that amount for the 2013 season, yet it's also hard to picture them allowing a former No. 3 overall selection to walk as well.
