Well I'm not sure how true is your statement, but I kinda disagree about this. Slower tactics don't necessarily have to be for strong passers. Back in my first few seasons, my PGs have the best handling in the country, but their passing sucks (I had to train their shooting at the expense of passing after I found out that no matter how good your offensive flow is, if you got lousy shooters, you still lose). Yet I've never had any problem facing FCP teams with slow tactics. Any explanation here?
What i am saying, is that TO can be produced by 2 factors. Bad handling or bad passing or both. So fast tactics using less passing, and its more on the respective player to create his scoring opportunities than the others create them for him (as the slower paced tactics). Having both of course, is giving you the chance to decide what to play. I am saying exactly what manual says, plus giving the importance of passing for the slower tactics.
Now about the passing/slower tactics. From my experience playing both RnG/motion i saw the % of my players going up considerably. In sum up i will take less shooting/more passing, and i still believe that i will have the same result (or better) with lower salary. On my PG +1 on JS means 12k salary more, +2 on PA no salary affect...
Now about the explanation that you are asking, i dont have either any problems with that. Why? 1st i consider FCP the worse D tactic on the game, 2nd since the players getting tired faster, so you need good bench to keep it up, 3rd if you are much better team, you will win anyway.
