This wasn't like the Pacquiao fight. Arguably this fight proves that the rules of boxing do not accord with what fans consider to be good boxing. It is actually very rare that the boxer who appears to be the better fighter "loses" on the scorecards. It was still a very close fight either way, and just as Provodnikov said, everyone saw what happened, and he will be appreciated for it regardless of how the rules are supposed to be followed.
Of course, if the referee had properly scored that knockdown in round one, it would have been even closer (I forget, would that have made it a majority draw?)
