I woke up early this morning and watched the 1994 USO match beteen Agassi and Chang. Enough said about Agassi... but I am always impressed by Chang's play. Fast, smart, resilent, solid net game too. Yet, people say he lacked 'power' 'knockout weapon' etc. So, I wonder if he had a physique/power of Boris Becker, would he have been 'almost invincible' (I mean something like Federer's level) during 1989-mid/late 1990s? That would have changed his playing style, too but to make it simple, it's still Chang but with much bigger body and power. Would it have threaten Sampras' reign?
