Irrespective of his credentials...which are far better than many on this forum might recognize...Kellen will be in a no-win situation.
My view:
1. Moore is not a culture changer.
2. He's not an alpha, though he's very good and bright and has excelled as OC.
3. NO is a small market...the type of team the NFL feeds to others as shark chum.
Maybe forces will emerge to clean up the NFL. Until then...low revenue/low attention teams like the Jags, Colts, Cards, Saints and others have a HARD CEILING.
1% chance of success.
