As strange as this may sound, the second biggest loss for the Cardinals was Karlos Dansby.
Before you react, honestly think about it.
Antrel Rolle was replaced. Sure he was good, but not that good.
Anquan Boldin didn't want to be in Arizona. And Early Doucet looks like a great replacement.
And of course there's Kurt Warner, who's the biggest loss for Arizona obviously.
But the Cardinals are going to have a tough time, at least this season, replacing Dansby.
Lenon can ease the pain by having a great season. Lenon has never had a big role in the system the Cardinals run, a 3-4 hybrid, but has played middle linebacker in a 4-3 with both the Rams and the Lions.
As a side note, the Cardinals don't have a great defense, but surely Lenon will enjoy playing for Arizona's defense as opposed to those two.
Lenon did enjoy moderate success in Detroit and St. Louis, but for the Cardinals defense to excel, the other middle linebacker has to be ready to roam around and create havoc, because Gerald Hayes will do a lot more run-stuffing.
If Lenon is able to do this, the Cardinals defense could be even better than it was last year.
