MINNEAPOLIS — Minnesota and Jacksonville had the top two defenses in the NFL last season, a major reason why the Vikings and Jaguars reached their respective conference championship games.

Two joint practices and one exhibition game produced yet more evidence of the exceptional skill and sound scheme each team has on that side of the ball.

Yannick Ngakoue had an 11-yard sack that helped Jacksonville hold Kirk Cousins and Minnesota’s starting offense to three completions and three points, before the Jaguars reserves rallied for a 14-10 victory over the Vikings on Saturday.

“The defense got after them pretty good, and their defense got after us pretty good,” Vikings coach Mike Zimmer said. “That’s kind of how it looked all week.”

Cousins was crisp in his only series last week , but the Vikings went three-and-out on two of their four possessions with their new quarterback. Latavius Murray’s second fumble, stripped by Malik Jackson and recovered by Calais Campbell, stopped another drive. Cousins finished just 3 for 8 for 12 yards.

“Frankly, I think that’s what we need and maybe want at this time of year,” Cousins said. “Nobody feeling comfortable.”

About all the ever-demanding Zimmer was pleased with was that the Vikings didn’t actually win.
