The NFC North was the only division in the NFL where all four teams finished with a winning record last season, and the Vikings narrowly escaped a last-place finish by beating the Detroit Lions last Christmas. After the rest of the division reloaded this past offseason, the North will be tight again this season. The Vikings won’t face the Lions until a trip to Ford Field on Nov. 1, but Mays’s injury still is significant. Vikings’ young defensive line could exploit Lions’ interior concernsThe late matchups with the Lions mean the Vikings will likely see Mays at some point this season. If the Lions' offensive line shuffling continues, it could be ripe for any opposing pass rush, even with Penei Sewell moving over to left tackle after Taylor Decker’s release this spring.
