When you see 16 on the clock you still have a margin I think, cause the refs rarely call it. I've seen Kawhi Leonard in yesterday's game clearly violating the rule (15 sec on the clock) and they didn't care.
And if you ask me, it's not such a big deal. you've got 24 seconds to shoot, and basically you've got to attack, if you want to lose time, it's your problem.
Now about IT, I don't mind seeing that because I don't like rushed shots and I think it happends too often. Also, I think he's slow only when we are ahead and that makes sense.
So... meh. refs don't care anyway as long as you don't take 10 seconds to cross court.
