Health: Kirk Cousins needs to prolong his streak of 49 consecutive starts. Dalvin Cook is capable of being one of the NFL’s top dual-threat backs, if healthy. And the offensive line’s depth already is strained by injuries to Nick Easton and Pat Elflein.

 

Red-zone success: It’s no coincidence four of the NFL’s top five red-zone offenses last season — the Eagles, Vikings, Patriots and Jaguars — made conference championship appearances. Vikings coordinator John DeFilippo had a hand in Philadelphia’s game planning, and he’ll need to make his mark in Minnesota.

 

O-line’s pass protection: Cousins has a mediocre history of performing under pressure. Case Keenum faced a top-10 pressure rate last season, though he allowed that to produce only 22 sacks.

 

Time of possession: Only the Super Bowl champion Eagles exceeded the Vikings’ average possession of 32 minutes, 26 seconds per game last season. Moving the chains is key to keeping the defense fresh.
