2015 season
On March 11, 2015, Maclin signed a
five–year, $55 million contract with the
Kansas City Chiefs. He finished the season with a career high 87 catches for 1,088 receiving yards and 8 touchdown catches.
The Chiefs, who had gone 11-5 after winning 10 straight, advanced to the playoffs, where things didn't go as well for Maclin. In a 30-0 shutout of the
Houston Texans, Maclin started out slow, but started to get into a rhythm in the 3rd quarter, with 3 catches for 29 yards, before he suffered a high ankle sprain that kept him out for the rest of the game.
Maclin, who many thought wouldn't play at all against the
New England Patriots in the divisional round, was listed as active, but he played very limited snaps and was taken out almost entirely after the first half, finishing with 2 catches on 3 targets for 23 yards.
Maclin was ranked as the 93rd best player in the NFL by his fellow players on the
NFL Top 100 Players of 2016.
2016 season
Maclin started 12 games in 2016, recording career-lows of 44 receptions for 536 yards and two touchdowns.

Maclin’s release, since it came after June 1, clears $10 million in cap room for the Chiefs, who had approximately $3.5 million prior to his release, according to the NFL Players Association.
The Chiefs will also have $2.4 million in dead money this year due to the release of Maclin, and $4.8 million in 2018. The Chiefs will still save a net of $8.6 million on the cap in 2018, which is needed; according to OverTheCap.com, the Chiefs are still over the projected 2018 salary cap of $178 million by approximately $638,000, even with Maclin’s release.
But for the Chiefs, there are other benefits to releasing Maclin now, other than saving approximately $32 million in non-guaranteed cash — including part of a $250,000 workout bonus he won’t receive due to the timing of his release – they owed him from 2017 through 2019.
Maclin, who just turned 29, would figure to find a job fairly easy. He’s looked spry in offseason practices, and has worked consistently with the first-string offense in offseason workouts.
