I don't agree on your reasoning about blocking working on help defence.I think that when a player shoots,it's considered only the blocking skill of his direct defender,because it would have been evident someway if more shotblockers would affect the same shot(we should have seen some blocked shots made by a player that wasn't the direct adversary of the shooter in that single action,right?)
i am pretty one the BB said something like "X rotates over to help"(or something like that) is an SB event, so you could this one for granted. So lot of Blocked shot should be on help d.
Ok,thanks,this Sb event however should be one of those events where Sb is used in combination with ID,that still remains the main skill
So Sb should act in more than 20-25% of the times,maybe 25-30 or something similar...this improves a little bit SB reputation,but not enough to make any of my point someway invalid
When someone ask you "you would prefer to have a better defence on 5-7 adversary shots,or have an additional 80k player to use in a game?",the answer should still be the same ;D
