It's too bad that this awakening didn't happen before the attempts to curtail the clay court season were made, a move spearheaded by the US. They wanted to eliminate Monte Carlo altogether but there was huge push back and the tournament ended up being downgraded. There is still a lot of ill will towards the US by European and South American players because of that effort. That said I'm glad Isner and Querrey are trying. I've even seen Venus and Serena sliding more in their matches, and they're doing it correctly.
