GGG to stop him 9 or 10. Brook to be very competitive through 6 rounds before slowing down and GGG getting the eventual stoppage.
Brook will grab, hold and count on his personal referee to allow such, Brook's judges and boxing commission will do all they can to help him, but it still won't be enough....................Golovkin mid to late rounds................
Here is my prefight summary and prediction for today's Golovkin vs. Brook matchup: http://tinyurl.com/j48j9hv
