Gennady Golovkin of Kazakhstan will be in the most important prize-fight of his career Saturday when he defends his middleweight title against Matthew Macklin at Foxwoods Resort in Mashantucket, Conn. (on HBO). But according to Abel Sanchez, Golovkin's trainer, Macklin won't be Golovkin's most difficult opponent.
"No, I don't think so," Sanchez said via telephone Tuesday from New York City. "I think (Grzegorz) Proksa was our toughest opponent to date, and I'll tell you why. I think that our first fight on HBO, Gennady's trying to impress, trying to do things that he should not have done. He should have just stuck to what we practiced. That was the first thing.
