Miami Heat star Jimmy Butler is widely considered as one of the best defenders in the league today. Recently, the four-time All-Defensive team member penned an article for The Players’ Tribune, wherein he openly spoke about some of the most challenging players he’s ever had to guard throughout his entire career.

Jimmy Butler starts things off with no less than Los Angeles Lakers superstar LeBron James.

When you talk about a combination of speed and athleticism, plus a combo of strength and explosiveness, you gotta start with LeBron. He’s one of the most dynamic players this league has ever seen. He can literally play every position on the court and be elite at all of them. That makes him a matchup nightmare because the smaller, faster guys can’t body up with him — he just overpowers them — and the bigger guys who can bang with him in the post aren’t quick enough to keep him from getting to the rim.
