Definitely looks more like "repeat" than "revenge." Their first fight is as far from a fluke as it gets.
I find typically the rematch will follow the way of the first fight. I thought Kovalev was winning the first one, but Alvarez is gunna know all he has to do is time Kovalev once he gets tired.
Such polls should offers the option "goes to the cards". Decision, means nothing. Or at least offer draw, ofc that too means very little. So i am going with to the cards for the rematch. Alvarez, ko aside, was being broken down slowly by Kovalev's power. However, Alvarez when he stayed active and jabbed was winning every exchanges. I expect Alvarez to adjust and not to repeat past mistakes and Kov to stay the same. But that also means Alvarez wont need to rush in. So to the cards, que sera sera.
