Jeremy Evans was told explicitly by opponent Terrence Ross to not use a prop, but he couldn't help himself. The Utah Jazz center brought out a covered canvas by the rim, then jumped over it while doing a left-handed windmill. He completed it on the first try, then took off the cover to reveal a painting of himself that he proceeded to sign.
It had props, but if there was voting, I'd still give it a 50.
This is how you correctly use a prop. Rather than make it the center of your dunk, it should complement what you're doing already. Evans ended up doing an impressive dunk even without the prop present, then topped it off by signing the photo.
SB NATION'S SCORE
This merited a 50. At the very least, it merited a perfect score more than any of the dunks completed in the first round of the competition.
