So:
Zwerev did a lot of the right things in this match regarding an aggressive playing style. In some situations, it worked well; in others, less so.
So, back to the starting question: was Toni right?
Yes, in terms of playing more aggressively—but not in every situation, all the time. Prior actions and circumstances should be taken into consideration.
The statement that opponents might only get two breaks against Zwerev is also true for many players, but not necessarily for Sinner and Alcaraz.
