Nothing significant needs to change.Hopefully they can improve their passing game whether its schemes, player personel, etc .The offense has been effecient and high scoring the last two years. You dont change the identity of this offense. Again, the Ravens offense under Flacco ran into problems when they handed him the keys and went away from Air Coryell under Cameron. You can't try to do too much when this offense has been very good as is.
"You know the definition of insanity? Doing the same thing over and over, expecting a different result."
Now, I'm not advocating we change the offense as a whole. Or we even touch the running game. That would be stupid.
What I am advocating for, is a complete overhaul of the passing concepts. You can keep the same offense. The same formations. The same exact running concepts and run/pass splits. To say we need to stop running the same run game scheme is idiotic. It very clearly works. Hell, it doesn't just work, at times it's flat out dominant.
What DOES need to change are the route concepts. Honestly, that's not even that big of a change. Roman needs someone who can come in, take his formations, and design route concepts that work. Running 2 or 3 guys to the same area doesn't work. And it will never work. You need depth. You need separation. Teams that give us trouble run zone concepts almost exclusively. Tennessee got burned when they tried to get cute and go man. Every time they did, Lamar took off and killed them. Buffalo didn't make that mistake. They stacked the line and played zone concepts, that covered the parts of the field they knew Roman liked to throw. When you consistently have 2 or 3 guys running to the same spot, you can freely blitz an extra man, knowing you can effectively cover 2 or 3 guys with one person.
Another problem I had, and Warner also highlighted. Lamars slot receiver, and dump off option, was Patrick Ricard. I love Ricard. But he has no business being in the slot. Especially when you have Duvernay, Snead, and Proche who can all run the same routes as Ricard, better, and be a lot more effective after the catch.
