Have you noticed a huge improvement in Roger's second serve since IW?
In IW, and so far in Miami, he's winning like 75% of points on his second serve, even against Rafa or Stan, which was not the case in the AO.
I think he's using a lot more the kickserve, which has an impressive effectiveness here with the slow HC, with high boucing.
