I don't know the leagues exact finances, not going down that rabbit hole, but you seem to keep implying this is just a vacuous cash grab, playing out the string merely to meet television quotas, and not much else.
My thinking is, if we are going to do this, lets have compelling and interesting basketball. Let's be creative, NBA changed things up with the all Star game. Why not try something with the end of the season for non playoff teams? They made the hurculean effort to come back after all. By the time July rolls around, the voices pleading "it's just too risky" will no longer be drowning everyone else out.
