Truthfully, Alexander hasn't been good this season. Like average or very slightly worse than average. Though still better than his replacements.

Campbell might of helped, but it's the linemen, as I've been saying, this defense has gone up and down based the talent of the OL they have faced.

Lions have one of the best OL, so the defense will go down. And that's partly the Packers players and partly the scheme which focus on coverage, which leaves the front short handed and you need great talent up front to try to handle that. Packers don't have great talent.
