Rematches used to be something when the first fight was a classic, someone got better, etc. now they are just because a fight was kind of close, but boring as hell. or a fighter likes the other one, so he wants to give him a payday. every fight doesnt demand a rematch, especially this one in which winning or not, Kovalev fought like ****
Kovalev has become a very pathetic and sad case, and I hate to say that about any boxer, let alone one who used to be such a beast. He's obviously got issues in his life which he needs to sort out.
Seriously now, if you effectively admit that you went into a fight knowing you couldn't win it, that kind of forfeits your right to demand a rematch, no?
