When it comes to modern-day defenders in the NBA, number one has to be Draymond Green. The word tenacity doesn't even come close to describing the level of intensity he plays with. If the Kings are serious about building their defensive profile, he's the man to do it.
The 35-year-old power forward has been in the league since 2012, when he was drafted by the Golden State Warriors. He was a key element in the dynasty built over those years, playing a big part in all four NBA Championship victories. Draymond is a big reason why Golden State won those titles.
