Not from what I've seen. Here's a site mail I sent to one of the Veteran Coaches about this same issue. I had a game the other night where I double teamed a guy the whole game and he still went off on me.

I have another question for you. If you look at my game last night, please tell me which view point is correct from my coaches corner today between me and MJP. If MJP is correct, that's a bunch of crap that needs to be pointed out to Seble and fixed.

The double team is pretty much the useless aspect of HD Court, unfortunately it does just about nothing to stop a star player.

That's a total bunch of Crap!! There ain't no frickin way Dinardo goes 7-11 with 22 points, when he has a double team on him the whole game.

Court

I'm playing a 5-walkon Sim team tonight where one player is putting up 19-20 PPG - I'll try out a double-team in my HCP/zone and see what happens.

OK Cornfused, sounds good. Just for information purposes, I was playing Man to Man and Double Teaming his PG the whole game.

I think the big problem is the my PG RULES WOOOOO 

The doubleteam is pretty useless from what I've seen, but this particular PG is going to be All American and very possibly first team. Sometimes even a double team can't stop a guy like that.

Perfect example of the "Self Love" and "Self Infatuation" I have to put up with every day in my coaches corner. LOL

Double-team generally limits distribution. How many shots per game was the PG taking prior to this game and how many shots did he take compared to his teammates?

Looking at shots per minute:  In all games outside this one he averages .572 posessions per minute - in this game he had .46875 posessions per minute.    So he had about 83% of his normal posessions you woudl expect based on minutes played.

I think the problem is people don't fully understand how a double team is supposed to work. It's not supposed to be every single time a player has the ball in his hands he has two players on him, in a M2M the double is coming from a defender already guarding somebody else so it's a help double sometimes it's late, sometimes they can't get there. It's not like double covering a WR, most of the time in basketball a player facing a double team will be played 1 on 1.

And I imagine the effects of a double team also depend on the quality of the people double teaming.
