Watching St. Louis beat Arizona last night, it was kind of sickening to think the Lions might have been able to get both of Cortland Finnegan and Janoris Jenkins. Even one would have been nice.
Jenkis has unbelievable cover skills and recovery speed. Finnegan is a real tough guy back there and a big hitter. Both can tackle. Even one of those guys paired with Houston would have been a tremendous upgrade.
But it is what it is. And what it is ... is a defensive line that is undermined by very soft coverage and poor tackling. Jacob Lacey so far has shown why the Colts dumped him - he cannot tackle or locate balls in the air. That is the same problem with the two rookies, Green and Bentley. The play of the safeties Spievey, Wendling and Coleman is really worrisome. Missed assignments, bad angles and missed tackles are more common than not.
Overall, I would say that the Lions issues on defense at DB are really a function of poor player procurement. That is on Mayhew and Schwartz. And it is clear they know they have problems or they would not have traded for one guy (Kevin Barnes, who they now have cut) and then claimed a guy off waivers (Jerome Murphy who they also ended up cutting) since the start of September.
Delmas will certainly help, but this team will have to score a ton to even get to 8-8.
