So you are saying I'm going to need a bunch of OD in order for this experiment to work? By running a 3-2 wouldn't that put even more pressure on the guards forcing them to make bad passes which would result in a not so good shot making it more likely to get blocked. I really never understood how DR and PA worked in the GE.
My experiences in the past with 3-2 zones, are that the other team always finds a way to match-up their shots/passes mostly against your weakest OD of the 3 defenders.
Same for 2-3 zone. They always attack the weakest one.
