MINNEAPOLIS -- The Detroit Lions maintained their hold on the NFC North with a 14-7 win Sunday against the Minnesota Vikings. Here are three things we learned in the win.

The Lions have one of the deepest safety groups in the league. I don't think anyone was surprised by Glover Quin coming up with that strip to seal the game, and listening to him break it down after the game -- talking about how he anticipated the ball would come loose because of the way Adam Thielen tried to tuck it after making the catch -- explains so much about why he's able to come up with so many turnovers. The guy is one of the best in the business because he's just so smart. And Tavon Wilson is a solid player alongside him. But where we're really learning about this group is Miles Killebrew, who continues to shine in an expanded role. He played 45 snaps against Minnesota, 23 of which wound up being in coverage. And he didn't allow a single reception. He dropped that pick in the end zone, of course, but was otherwise flawless. And he's Detroit No. 3 safety. In fact, ProFootballFocus ranks him 13th at the position. And Quin is third. Seattle is the only other team with two safeties in the top 15. Yeah. This group's deep.

The Lions are deep at tight end. They've wanted to go multiple players deep at the position for a while now, but never really had the personnel to pull it off. So they made it a priority in the offseason, signing Darren Fells in free agency and selecting Michael Roberts in the fourth round of the draft. On Sunday, we saw our first real glimpse into the possibilities. With Minnesota's pass rush knocking the crap out of Matthew Stafford, he kept checking down to the tight end -- and it wasn't even Eric Ebron. Fells is known more for his blocking, which helped hold off the Vikings' rush, but he also caught four passes in the first quarter alone. That matched a game high for his career. And then in the second half, Roberts caught a 15-yard pass in the red zone that led to Detroit's go-ahead touchdown. Those guys caught five of their six targets, offering some terrific support behind the struggling Ebron. In fact, Fells is playing at a higher level than the first-round pick all together.

The Lions can bounce back from adversity. Last week was rough week, given the way they lost to Atlanta. Then they were going on the road to face a co-division leader -- and one that features one of the most unforgiving defensive fronts. Matthew Stafford was batted around, too, and so was the offensive line. But nobody quit. When they lost the lead at the end of the first half, nobody panicked. They just went to work. They turned over Minnesota twice to open the second half, took their 14-7 lead, then held on. It wasn't fancy, and there weren't many big plays. They just played tougher, and they won because of it.
