So tactics and OF are independent, as I read this.
Same paragraph:
Putting on a full court press will increase the number of turnovers you force, but will also give opponents with good ball handling skills easy looks at the hoop.
So maybe tactics do influence the OF, because the offensive flow will be better when your opponent does not execute FCP well.
But it's the same story for almost everything regarding the game-engine. Nothing is for sure, it's just what you believe. There are no facts yet, just a general discription in the rules.
What you cite is a description of the defensive tactic called 'Full Court Press.' It has nothing to do with the Offensive Flow rating. Anyone who uses FCP will create a few more turnovers for his opponent while giving up a few easy baskets. That is how FCP works in reality.
From the rules:
The better offensive flow you have, the more high quality assisted shots you will get.
This sentence is very clear. OF improves every offensive tactic. So it is independent of your offensive tactical and choice. And your opponent's defensive tactical choice.
Check out the OF of the top teams in USA D1. There OF rating against other D1 teams is insignificantly different from the ratings they achieve in Cup games against DV bot teams. This is typical at all levels and countries that I have checked out. Not everyone, to be sure, but more than anyone else has taken the time to look at, other than a BB, I'm willing to bet.
I've seen a few OFs reach Mediocre, but most good teams are only Inept no matter who they play. Why is this? Why would a player like a cited in the first post not result in at least Mediocre OF?
Again from the rules:
Offensive Flow (how well the offense produces assists, avoids turnovers): point guard weighted very heavily, shooting guard weighted medium, small forward weighted medium.
A guy like this should make a significant difference. And he's not.
I'd like to understand why.
