Hmmm...Grass below clay?
Before the Fedal era, and especially during the Sampras/Agassi era, clay was an afterthought. It was Nadal's ability to break out of the clay court specialist mold, and Federer's ability to succeed on clay that has raised clay's profile, at least since the 90s (when I started following tennis).
