For the dunk contest you must first choose someone with dunks over 90 (LeBron Kobe Wade ect.) Then, start out with your first dunk as a long jump or a dunk using the square button. On your second dunk, go under your legs or around your back. Finally, for your last dunk alley-oop it. (first dunk usually gets you a 35-45)(second dunk 40's)(third dunk 45 or higher) usually^^
