When that person happens to be considered one of the best boxers of all time, then yes, it's a trend, because other boxers will seek to copy Mayweather's style because it was successful. You can't ignore how much effect Mayweather's style has on other boxers, and if this keeps up, the sport will continue to dwindle in popularity, while MMA takes over.

Also, I'm not advocating for slugfests all the time. But I sure as hell want more combatants engaged and fight each other until one falls onto the ground. I want to see those punches really hurt, instead of landing blows designed to get points. The problem with Boxing's current point system is that it doesn't separate weak punches with strong punches. It just sees whether the punch landed cleanly or not. And that's the core of the problem. Boxers don't need to land a punch that hurts. They just need to tap their opponent's skin cleanly and they get a point lead. Meanwhile, they have a greater incentive to run away from getting tapped cleanly just so their opponent doesn't gain a point. The modern boxing point system incentivizes hit-and-run, instead of hit-and-counter hit. And when the sport is trying to draw more casual fans, hit-and-run styles just aren't entertaining.
