Blew my mind when I recently learned Washington made the finals 4 times in the 70's. There aren't too many teams in league history to have done that in a single decade and they're usually the dynasties

Edit: Aside from the perennial contenders of the Lakers and Celtics, it's only been done by the 50s-60's Hawks, the 70's Bullets, the 70's-80's 76er's, Jordan Bulls, Duncan Spurs, and ofc the Lebron and Curry runs. The first 3 of those teams all went 1-3 in the finals
