Remember when Drake was the biggest Kentucky Wildcats fan on the planet??
The dude's leanin' more towards Duke, now ... 'cause Drizzy's added a FULL R.J. Barrett Montverde Academy basketball uniform to his insane collection ... and he's proudly showin' it off.
We all know the 6 God has a TON of rare prep jerseys -- from John Wall to Boogie Cousins to Barrett's Duke teammate Zion Williamson.
The newest addition might leave some people scratching their heads considering Drake's a big BBN fanboy ... and Barrett's tearing it up for the Blue Devils this season.
