Tim Duncan can still take you down in the post and take your lunch money. He put on a show after practice with the San Antonio Spurs as he schooled some of the Spurs big men on their post game. He looks like the Tim Duncan we all remember.

That quick spin before kissing it off the glass was just disrespectful. On the next play, he drives before drawing the foul before finally burying the mid-range jumper. Duncan still has some of those pretty post moves that made him such a joy to watch.

Unfortunately, this doesn't mean Duncan is planning a comeback any time soon.

Duncan, 42, has nothing left to prove. The 15-time All-Star is a lock for the Hall of Fame. He's a five-time NBA champion, three-time Finals MVP, and two-time league MVP. Duncan will go down as a top-10 player of all time.

With all that in mind, it's really no surprise that he can come back into the gym as a 42-year-old and school a few 20-somethings on their post game. The man was one of the best to ever do it.

But perhaps a career in coaching is in his future. Popovich and Duncan are extremely close, and it wouldn't be surprising to see Duncan join the Spurs organization in an official capacity in the future. But until then, Duncan will dominate the young bucks in the paint after practice.
