it works better vs run and gun and push the ball because u will be guardin your man the whole court and he wont be able to get open with his speed.
This is bogus and, all in all, false. There is no particular reason why FCP should work better against these particular tactics.
that maybe the only point he is right, there is one reason ;) The prohability is higher to make an fault in handling and passing with fast tactics, and a full court press mostly works in the first seconds, so that you don't profitate from more contacts with slow tactics.
The other think what could be right is the stamina one, i cann't proof it but i would say that this is right because i believe you loosing an specific amount of stamina for each offense you are run.
