Video: Paul Pierce takes Fab Melo to school

NBA practices are guarded events. Sometimes media and rarely, fans, get to see the final minutes but for the most part, what goes on stays there. And there are a lot of moments missed that fans would likely find interesting, or at least fun. Like this.

Celtics rookie Fab Melo was working on his post moves at the end of practice, and you'll see future-Hall-of-Fame legend Paul Pierce notice him ... then go over and start guarding the kiddo. Then it's Melo's turn to try and stop a player much older and much smaller than him. And the results are hilarious.

"All day," indeed.
