Maybe it's because the guys in the olden days already attempted most of the dunks, or maybe it's because stars are too overpaid to give a fuck, or maybe it's because the NBA changes the rules up every hour, or maybe it's because guys don't respect the art anymore?

See, we don't mind seeing the same dunks, as long as they're done with grace and style. (see: Josh Smith) And it's a crime against humanity that LeBron James would rather do creative dunks in the layup line before games instead of doing them in the Dunk Contest. You couldn't get away that shit in the '90s.
