The deal will pay Boss $9 million over that span, which will officially make him the highest paid tight end on KC's roster.
After examining his new deal, I think that KC made a smart move by landing the ex-Giant for only $3 million a year, considering that it was an area that the Chiefs lacked depth in. He also has the potential to step in and become a starter for them if Moeaki has any setbacks from his injury in the near future.
Signing Boss was also a move that the Chiefs had to make after their struggles at the tight end position last season.
Veteran Leonard Pope led all Chiefs TEs last season with just 250 receiving yards for the entire year.
Part of the reason for KC's struggles at that position last year were due to starter Tony Moeaki's torn ACL in the preseason that ended his season before it began.
With Moeaki's past injury issues, Kansas City decided that they needed to bring in another option at tight end by inking Kevin Boss to a deal.
Not only does his addition provide insurance at tight end for the Chiefs in 2012 and beyond, but it also gives KC's offense the flexibility to use more two TE sets in the future with both Moeaki and Boss.
How many receiving yards will Boss have for the Chiefs in 2012?
Boss also has a reputation as not only a solid blocker, but also a more-than-capable pass-catcher as well.
Last season, he caught 28 passes for 368 yards and three touchdowns as a member of the Oakland Raiders.
Even though these numbers might not excite many Chiefs fans, he would have been the No. 1 receiving TE for KC last season, and it wouldn't have been very close.
Overall, I think that this was a solid signing by the Chiefs, as Boss can come in and impact KC's passing offense in 2012.
Since KC was able to sign a quality tight end to a cheaper, three-year deal, I believe that this move deserves an A grade.
