There is something about the NBA Playoffs that just brings us back to the classic days of professional basketball. Different eras where the hand-check rule wasn’t existent, legends defied gravity, and today’s stars were just being drafted or sitting on dad’s lap during an All-Star Weekend game. Now that's what you call the good old days.

This year's first round is already looking like a highlight real of the past—culminating in some of the most controversial calls, memorable plays, scoring performances, and upsets ever witnessed (Did you really expect the Wizards to beat the Bulls?). It’s this same action that has encouraged die-hard fans to jump on Instagram and share some iconic images of their favorite players and teams from over the past several decades. Time to suit up as we offer up this sweet retro collection of 50 Classic NBA Photos We Found on Instagram.
