I don't get that idea from that quote in the least. Pitta is saying the SYSTEM is garbage, in a nice way. His statement is "It's difficult to play quarterback under those circumstances". He even says the offensive philosophy is the problem which falls on the OC.
Personally, here is what should happen but won't. Fire Marty, give Roman his shot with a promotion (temporary). Let Joe work with Roman, but hand this offense off to Joe. He's the captain on the field period. You'll see what you have with Roman and you'll know exactly where you stand with Joe. Or, you can do what this FO WILL do and has done for years, remain status quo and remain mediocre at best and garbage most of the time. Refusing to move forward into this century of football and continuing to ignore the offense in some attempt to relive glory days of defensive domination that really can't be gotten back on that same level.
