You don't need to change the format...you just need the judges to stop giving everything a 10. I thought Lavine had a great performance, but they shouldn't have all been 50s. I'd be okay with a 0-100 scale (or introduce a decimal system like the Olympics), but I feel like we'd just end up in the same situation. Maybe let them each do 3 dunks, then the judges vote for a winner? I don't know...in the end, this isn't some huge important thing, but we saw how Shaq got boo'd for giving those early dunks 9s. A 10(0) should be Vince's 360 windmill. No dunk should get a perfect score unless it hits that mark, but none of these judges want to be boo'd so we end up with everything being 50s.
