He threw just 10 touchdowns and nine interceptions to go along with a QB rating of 76.6 in just nine starts for the year. To make matters worse, Cassel broke his hand in Week 10, which subsequently ended his campaign prematurely.
This year, he hopes to greatly improve on those numbers with the help of another full offseason to heal his hand, as well as several new offensive pieces that have been added to this roster through free agency and the draft.
Here are five bold predictions for KC's starting signal-caller in 2012.
Matt Cassel has never thrown for 30-plus touchdowns during his time in the NFL. That being said, I have him reaching that number in 2012.
Even though many believe that KC will be a run-first offense once again this season, it's not out of the question for Cassel to throw 30 touchdowns or more considering the talented core of wide receivers and tight ends that he will be working with.
This may not seem like a very bold prediction when you consider that Cassel likes to take chances at times and has already thrown 15-plus interceptions in a season before. However, when you examine the surrounding talent that he will have around him in the passing game this year, it becomes much more bold.
Even with the 15 picks, I've still predicted his TD/INT ratio to be sitting around 2:1 in 2012.
This is a far cry from where it's been in two out of the past three years for the Tom Brady's former protege.
There's no question that Matt Cassel is an emotional guy when he is on the football field. That might not bode so well for him this year when you consider that he will be dealing with another fiery offensive coach in Brian Daboll.
Although I don't expect it to happen frequently throughout the season, don't be surprised if Daboll and Cassel have their own disagreements on the sidelines this year for the Chiefs.
It's been way too long since this organization has won a playoff game.
Next year will make it 20 years since Hall of Famer Joe Montana won two postseason games for KC back in the '93 season.
That being said, I am predicting that this year will be the year when Matt Cassel and this talented Chiefs team end the franchise's playoff drought, as they will notch at last one victory after the regular season this year.
This would be huge for Cassel's reputation in Kansas City, as he could go make the leap from unpopular QB to playoff hero in just one season's time.
The one and only time that Matt Cassel made the Pro Bowl was two season ago in 2010.
That year, he did everything right, posting career highs in touchdowns with 27 and passer rating with 93.0 mark.
After a down season last year, Cassel is back to full health again and will operate with easily his most talented and deepest offense in his time with Kansas City.
If he can play anywhere near the way he did during the '10 season, the former seventh-round pick will be headed to Hawaii next January for the second time in three years.
