Agreed. The last staff had 0 experience to fall back on. The GM, HC, OC, and DC were all 1st timers. Most of their staff was in roles for the 1st time as well. At the least, this is the anti Bears of the last 2 years.
I will say, IDC about the RB coach thing. Brown was supposedly one of McVay's top guys who absorbed a lot in LA. He also isn't a QB coach, so they have that guy and the OC that can have positive impacts on the rookie. I don't exactly know what the PGC does, but even if it's developing passing concepts, creating and exploiting mismatches and things like that, that's probably going to have a positive impact. But most likely, we won't know his impact on the QB. If the QB is good, his impact will be viewed positively.
