The Diesel put his stroke on display during a shootaround session with Home Team Hoops -- draining 3 point shots from all over the court.

At one point he calls himself, "Black Steph Curry."

For the record, Shaq only made one 3 point shot during his entire NBA career -- but judging by this video, maybe they shoulda let him shoot more?!

In all seriousness, Shaq looked pretty good on the court -- dunking, shooting, moving ... even busting out the LeBron James signature celebration move.
