You either get it or you don't, Flores created such a terrible offensive environment with his poor coaching staffs, his refusal to every let his offense just play football, his QB musical chairs and failure to every let his QB not be a play away from losing his job, and his offensive lines that featured almost entirely first and second year players, didn't get experience that he'll learn from in that time, that it's probably negative experience that will have to be unlearned.
Burrow/Herbert - these guys got to just play honest football from the get go without the shenanigans. Not the same for Tua.
