I think you're missing the point here. This rule change is purely about fan entertainment. The strategy is legit, it's just boring as hell, and makes the game less exciting to watch. Maybe you're right, and if they learned to shoot FT's, it would change. But they're not learning to do that, and the NBA feels the need to do something to take away a boring to watch aspect of the game. I don't find it boring at all, but yes I know the fan "outrage" over it being boring is what led to making a change. I doubt this leads to any more fans actually watching games when this strategy would normally be employed. But hey, angry twitter fans got their way.
