If basketball didn't work out, Blake Griffin coulda been a gymnast ... because the guy hit a PERFECT backflip during a beach session in Croatia -- and the whole thing was caught on video.
Blake's on vacation in Croatia with Clippers teammate DeAndre Jordan -- and both decided to test their acrobatics.
Blake went first -- killed it.
DeAndre went second ... NOT BAD EITHER ... but he's clearly the Aly Raisman to Blake's Gabby Douglas.
No disrespect to Aly.
