Matt Forte

David Johnson, a third-round pick out of Northern Iowa, ranked 15th in FCS in 2014, posting 1,553 rushing yards while finding the end zone 17 times. He is expected to make a big contribution to the Cardinals offense this season, according to his position coach, Stump Mitchell.

"He's a guy who has a lot of confidence in his ability to play," Mitchell told Doug and Wolf Thursday on Arizona Sports 98.7 FM. "He's coachable. He's a smart young man, he's physical. He's going to make Andre (Ellington) pick up his game when given the opportunity.

"He has excellent hands and he's a bigger target to throw the ball to. He's going to be a big piece of the puzzle before this season is said and done."

Mitchell gushed about Johnson's physicality, citing his ability to run over people as well as run around them. He also conjured a comparison to one of the NFL's most productive backs over the last five years.

"He reminds me a lot of (Chicago RB) Matt Forte," Mitchell said. "You can put him outside and use him as a receiver and he's a good runner."

The Cardinals have been trying to add a bigger back to complement Andre Ellington, and Johnson fits the bill. He does a lot of the same things as Ellington, so for now we're expecting that he'll serve in a backup capacity, but Mitchell sounds as if Johnson will play a larger role than a typical backup. We currently project him for around 147 touches.
