Last week, we posted about **how the Kansas City Chiefs defense impacted* the ability for them to rally from the 1-5 start only to storm into the playoffs at 11-5. This week, we review the offense.*

Reviewing the 2015 Chiefs offense has to start with quarterback Alex Smith, who, as has been noted, entered 2015 with the same head coach and offensive coordinator for the third year in a row for just the first time in his 11-year career.

As can be seen from this three-year look, Smith has continued to build upon each year in Andy Reid's West Coast offense.

The steady increase in his passer rating over the past three seasons leads one to believe that trend could continue in 2016.

A point about Smith to note was his willingness to rush during the 2015 season.

After only garnering just 254 yards rushing in 2014, Smith rebounded to run for more than 400 yards again in 2015, and it proved to be something to watch each game. The Chiefs were 7-2 when Smith rushed for 30 yards or more.

This was the first year Smith worked with wide receiver Jeremy Maclin, who came to the Chiefs via free agency last offseason. Maclin eclipsed 1,000 yards receiving for the second year in a row and had 8 touchdowns in his first season with Smith.

It's worth noting that the Chiefs lost running back Jamaal Charles in Week 5, but the tandem of Spencer Ware and Charcandrick West combined for 1,037 yards rushing and 11 total touchdowns on the season to fill the void.

As far as the offense as a whole, here is the point output from Week 7 forward, the stretch during which the Chiefs went 11-1:

Despite improved offensive success in 2015, only one Kansas City Chiefs offensive player was selected to the Pro Bowl in tight end Travis Kelce.

Kelce set career highs in targets (103), receptions (72) and yards receiving (875) in 2015, and he was rewarded this offseason with a contract extension for his efforts.
