We got him storming out of L.A.'s Staples Center moments after the boxers fought to a 12 round tie, and he called the outcome "bulls**t" because he thinks Wilder was robbed.
True enough, Wilder did knock down Fury twice -- including in the 12th -- but he got up both times.
Just like the match ... opinions are split. We also talked to boxer Andre Berto leaving the bout and he thought the result was fair, and he's looking forward to a rematch.
Michael Rappaport, on the other hand, wanted more from Deontay.
We know this ... if there is a rematch -- there's totally gonna be -- you can believe Ice Cube won't be watching! He's really not happy.
