Next it seems most of what can be done without having to toss a ball, or with the help of a teamate or props has already been done. You can only do so much in the few seconds of hangtime you have before the slam. So players will really have to start thinking through their dunks with a little creativity and showmanship. Dwight's "Superman" routine was a blast. Nate using former champ Spud Webb from the crowd was awesome. Amare using Steve Nash's soccer abilities was cool. Jordan clearing the runway for his free throw dunk. There are lotsa ways to get creative. Nate actually could've done something with the Cowboys Cheerleaders since they were already there. So it seems to me, dunks really have to be practiced from now on. We can't have the "I just do it and let creativity take over once in the air" dunks. We've seen 'em all.
I don't know the solution to the third point but the judging has to be more exciting. Yeah the personalities are there but maybe we can have an American Idol type setup where the judges actually tell the contestants how crappy or great their dunks were. Maybe some pointers as well to save the fans for further boredome so the dunkers will know what to try next.
I'm sure there are other improvement ideas out there but it'll definitely be more interesting if any of the aforementioned 3 suggestions are implemented.
