Delly was voted the dirtiest player in the NBA in a 2015 Los Angeles Times poll featuring NBA coaches, assistants, and players. Does it surprise you that little old Matthew Dellavedova would be voted as dirty? Perhaps you prefer to think of Delly as scrappy, which, you might notice, has a pretty strong correlation between little, white guards that are overly competitive and push the limits with their reckless play. And that’s what Dellavedova is — reckless.
Whether he’s being intentionally dirty or not doesn’t matter at some point when he’s consistently diving for loose balls and rolling up on guys ankles, like Kyle Korver. At some some point, reckless is just another synonym for dirty.
