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 in video.
Blake's on vacation in with Clippers teammate Deandre Jordan -- and both decided to test their acrobatic.
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.
