A win is a win is a win
Sunday's game was quite ugly for the Lions, but they once again proved that a solid defense can overcome a bad offense. Much like earlier in the season, the winning combination for the Lions was quite simple: let the defense make plays and do just enough offensively to win. In this case, the defense didn't do anything early, leading to the Lions falling into a 14-0 hole. However, the defense forced two interceptions that turned this game around, and the offense's one touchdown and three field goals proved to be enough for a victory.
The offense can't play like this and expect to win in the playoffs
It's okay to win ugly when you're playing a team like the Vikings, but the Lions can't play this poorly on offense if they want to go anywhere in the playoffs. That's assuming they get to the playoffs, of course, but the Lions offense undid all of the progress they made the previous two weeks with their performance on Sunday. Perhaps the Vikings just have their number -- the Lions had 255 total yards in their first meeting earlier in the season and only 233 total yards on Sunday -- but the Lions just seem lost against defenses that have a pulse (i.e. against teams other than the Chicago Bears and Tampa Bay Buccaneers).
Glover Quin and Jason Jones deserve a big pat on the back
Throughout the season, Glover Quin has seemingly made big plays on defense just when the Lions needed one. On Sunday, the latest example was his huge interception when the Lions were down 14-0. The pick and his ensuing return set up a Lions touchdown and really turned this game around for Detroit. He's now got six interceptions on the season and a pick in three straight games. He should be a Pro Bowler.
Jason Jones also deserves a round of applause for his performance on Sunday. In a span of three plays in the fourth quarter, Jones strip-sacked Teddy Bridgewater and blocked a field goal that would have given the Vikings a four-point lead. Those two plays helped keep the Lions only a point down, which allowed them to take the lead on their next possession. That blocked kick turned out to be the difference in this game.
