Well, I have to say I'm not all that surprised at the firing of Coach Spags. If you look at the stats of the Saints D this year, I mean, come on...It's literally the worst in NFL history.
So, who's up for the gig? A lot of fans have texted in that Lovie Smith should be the choice. But Lovie is not going to fit in with a 3-4 scheme. And, Smith has said he wants to be a head coach. It appears he's willing to take a year off to get that wish, so Smith may not be in the running.
I'll give you a name, though: Keith Butler, linebackers coach for the Steelers. He's coached under Dick Lebeau the last nine seasons. He knows the 3-4 scheme really well...and for him, it would be a vertical promotion, a serious step up.
As for personnel, the Saints already have a lot of guys who are suited to play a 3-4 D, such as Martez Wilson. He's a 3rd year linebacker who kind of fits the 3-4 OLB scheme.
And, this could mean that the Saints parts ways with Will Smith and Jonathan Vilma. Remember, when Vilma came here from the Jets, he was unhappy about the possibility of playing in a 3-4 defense. So, we shall see.
