I think this is just the process of the BB's trying to make the engine more and more realistic. We have to understand that this is complex and that the new features will need adjustments before everything is smooth. The fact that rebounds never went out of bounds was way too unrealistic. Now it was implemented, but it's happening a tad too often (also FT and close range shots do not go over the backboard and out). Still, for now we'll just have to live with the fact that our centers have hands like the Collins twins :P
As for the "player currently on the bench has a double-double", that's just a glitch in the commentary, it's not that big a deal...
