I dont agree he is shunned by the nfl.
Lots of coaches are Aholes and still have jobs. if you have what it takes, you'll make it.
By this logic, nfl owners and gms dont think he has what it takes. That's all it is.
Mularkey is not extinct.
He got another chance in Jacksonville in 2012.
He's now a TE coach for Tenn.
Again, if you're good, you'll have a job. Mularkey has shown to not be good enough for HC. That's all.
