You're correct sir.
K2 can only create a scheme that, at best, gives his offense situational advantages,
most of which (we'll give Kliff the benefit of the doubt that he'll bring in a new wrinkle or two), DCs have seen before.

Can you guess what I'm about to say?
Kingsbury has something that no other OC has had in the past. Kyler Murray might prove to be the perfect engine which allows K2's scheme to be truly dangerous.
It's scheme + personnel. Martz had a great idea, but he needed Warner + Faulk + Holt/Bruce to make it something truly special.
Disclaimer - I'm not saying that this season we'll have an offense that rivals the 1999 Rams. I hope that by the 2021 season we do however.
