The NFL’s top offense by our numbers is also the most improved.

Able to start all 16 games in 2015 after playing in only six 2014 games, Carson Palmer was a star by our numbers, finishing first in Passing NEP, second in Passing NEP per play, and third in Success Rate. His top three wide receivers -- Larry Fitzgerald, John Brown, and Michael Floyd -- all placed in the top 20 receivers in Target NEP, and the latter two were both part of the top 10 most efficient receivers, by Reception NEP per target.

With Andre Ellington on the shelf for much of the season, Chris Johnson was the workhorse of the backfield, and while he had four 100-yard games, he was one of the worst high-volume backs by Rushing NEP per play. After he succumbed to injury, the Cardinals unleashed David Johnson, who had a monster four-game stretch during the fantasy playoffs. David Johnson finished first in Rushing NEP and Rushing NEP per play among running backs with at least 100 carries.
