Just about every fan and pundit will tell you that the Detroit Lions had a very bad defense in 2019 and they would be correct. Most will also tell you a myriad of ways in which to address those needs, usually in the first round of the 2020 draft. However, to fix it, you need to identify what exactly it was that went wrong in the first place.
Those that see the lack of pass rush assume that an edge player opposite defensive end Trey Flowers is needed the most. Others see Damon Harrison‘s pending release along with the possibility of losing Mike Daniels and A’Shawn Robinson to free agency and pound the table for a top defensive tackle.
