Jason Kidd just shoveled a mountain full of praise on Luka Doncic ... saying the Dallas Mavericks superstar is not only better than Dirk Nowitzki -- but he's approaching Michael Jordan territory as well.
The Mavs head coach -- who won an NBA title with Dirk in 2011 -- made the eyebrow-raising comments on 97.1 The Freak's "The Downbeat" on Tuesday ... explaining he truly believes Doncic is already the best player to ever wear a Dallas uniform.
