^We are saying different things. System is different than formation - how you think positionally, tactically etc. So high press is a system. Formation is a subset of that. In my opinion, BB has not shown much system/tactical flexibility, and yes, he has used different formations.
Plus let's face it, "system" in the context of "he doesn't fit our system", is in world football a buzzword for "we don't like his attitude" or similar - in a lot of cases anyway.
We agree on the fact that we need 5-8 new starters to be a contender.
Suspect we disagree on how fast that can/will happen, and also on whether 2022 asset management has lengthened that process.
