yep, there's a reason people who call nadal a "pusher" or "moonballer" never provide any data to support such claims - data flies directly in the face of any such claims
for example, in this match, at this point:
winners - 32 to 25 nadal
net points - 21 to 13 nadal
he's the attacking player in this match
i've provided the australian open average forehand and backhand miles per hour data from several years ago several times in the past on talk TW (the only such data i'm aware of - will find it again shortly), and it supports nadal being a bigger hitting baseliner than federer (especially off the backhand wing)
but data doesn't matter to people who like to try to take away from nadal's incredible accomplishments, and who are probably in most instances absolute garbage athletes and 3.5 tennis players themselves who barely understand tennis
