Back to the topic about magsayo and Russell yes This is the big fight of Magsayo's career and they must be trained harder. In this fight I will bet magsayo too.
I remember watching Mark Magsayo's fight against Julio Ceja where the former landed a right hard punch on round 10 which sealed the deal and eventually won the entire fight. According to boxrec, Magsayo has an undefeated record of 23 wins. I do think that Gary Russell is a dangerous opponent given his destructive power, size, and speed on the ring.
There was this article that featured Magsayo, stating that this fight might be his biggest so far. Although I do fear for him, I am at full support towards this fight as I do believe that he will eventually come out as the winner at the end.
In a fight like this where a Filipino is a challenger for the championship, it's good to support and put our bet. I guess we all see how Magsayo adjusted in his previous fight, he did not get frustrated although his opponent is leading the scorecard, instead, he finds ways to make a convincing win and that is by knocking out his opponent. So, anything can happen in this fight, he might replicate that kind of victory although his opponent now is a champion.
Go with our "kabayan" no matter what the odds are. This is an opportunity for a Filipino fighter again to be a champion, and Magsayo has a shot in winning since his conditioning is very much efficient, he is actively fighting and now he is given a golden opportunity that he should not miss and has to win.
