Vikings’ special team coach Paul Ferraro gave his unit a grade of “inconsistent” for its play during Friday’s preseason game with Seattle.

He liked the runbacks by Darius Reynaud on a kick return and Jaymar Johnson on a punt return but said there is still a lot of work to be done.

“I expect to see improvement from Game 1 to Game 2 in the preseason,” Ferraro said. “That goes for both the return game and the cover game.”
