Tuesday open thread: Which Detroit Lions unit has been most disappointing thus far?

Unfortunately for the Detroit Lions, there are multiple reasons for their poor 3-5 start to the 2018 season. While the defense has probably been the worst offender, both the offense and special teams share plenty of blame in Detroit’s five losses this year.

Inside those units, just about every position has failed at some point this season, whether it be the quarterback, the secondary, the offensive and defensive lines, running backs, linebacker. You name it, and at some point the players have cost the team dearly.

However, some of these struggles could have been predicted. We knew the personnel on the defense wasn’t all that good, especially in that front seven.

So today’s Question of the Day has to do with expectations not meeting reality.

Which Detroit Lions unit has been most disappointing thus far?

My answer: To me, there’s absolutely no question: it’s the secondary.

In the offseason, Lions fans tended to overrate the secondary based on the play of their top defensive backs. Admittedly, Darius Slay, Quandre Diggs and Glover Quin entered the season at the top of their game.

However, the play of the Lions’ secondary has been nothing short of a disaster ever since the moment after Diggs took the first defensive play of the season for a pick-six. Detroit has proven that it has little talent at cornerback outside of Slay. Nevin Lawson and Teez Tabor have been getting routinely embarrassed on a week-to-week basis.

But nothing has been more disappointing, and quite frankly depressing, than watching Glover Quin, one of the most beloved defensive playmakers on the team, take a clear and obvious step back. It appears Father Time is finally catching up to Quin, and his electric reaction time has already fallen victim to age.

Right now, the Lions rank 30th in passer rating allowed (112.5) and 29th in yards per attempt allowed (8.5) and they have just three interception on the year (29th). Last season, this unit was fourth in interceptions, but it appears opposing quarterbacks have figured out that if you simply look away from Slay, you can complete passes all day.

Your turn.
