It's just a different beast. Everyone says it but unless you play Davis Cup I guess it's hard to really know what everyone's talking about.
Unfortunately, Gilly had to learn it the hard way this weekend.
I really hope this doesn't affect him mentally going forward. We've seen that happen far too many times (bad DC performances carrying forward). I don't think I've ever seen him so despondent.
Poor, Boo. Please don't lose before I get down to Indian Wells.
