Before Andy Roddick teamed up with Brad Gilbert he was a young, talented kid with loads of potential. After he hired Gilbert, he was giving Federer all he could handle and winning a slam. He made a huge mistake by canning the guy. Gilbert knows how to coach champions and Andy's game has been seriously missing the spark for almost two years. Whether Andy was not willing to adhere to Gilbert's work ethic or he just disagreed with the tactics Gilbert was trying to instill in him, he flamed out with that decision. I don't see him pulling himself out of this rut without some serious help.
