Justise Winslow has had an immediate impact for the Miami Heat on defense.

Winslow has defended LeBron James, James Harden, Paul George and DeMar DeRozan.

Among players to defend at least 50 field goal attempts this season, Winslow ranks tied for third in the NBA in defensive field goal percentage (32.8%) with San Antonio's Kawhi Leonard (32.8%) and Minnesota's Ricky Rubio (32.8).

In defensive field goal differential, Winslow ranks 12th in the NBA.

“He’s confusing me," said Chris Bosh. "You always want to kind of be easy on the rookies, but he is raising the bar every game with his maturity and ability and knack to play defense. I’ve never seen anything like it as long as I’ve been in this league from a rookie. He’s not making many mistakes. He’s playing solid defense. He’s already built like a tank. Him just being able to move his feet is helping us out a lot.”
