I love blocking shots in basketball. In my prime it was something I excelled at. I also love the switch hands in the air lay-up and the baseline bank shot.
And now, at 33 with a bad back and no longer able to reach down for steals, I love kicking the ball on defense. My feet have maintained their speed, so I can usually get a toe on any bounce pass. It's awesome when you do it four or five times in a game. I had one kid tell me I was cheating.

It's also nice to have a tall player guard me on defense - I'm 6'2, which is tall for a lot of pickup courts, so oftimes the other team's tallest player will guard me. I'll lounge around the perimeter, keeping him out of the paint. He'll eventually get lazy and start sagging. A quick cut to the free-throw line when it's game point, spot-up jumper, and his team sits.
It's the little things.
