Jersey, Jersey, Jersey:
Learn to "walk softly and carry a big stick".
I like this kid but he needs to work with Allen Fox and learn to control his emotions and his mouth. Federer, Nadal, Djoko, Murray, Tsonga, and all the others don't say anything antagonistic toward their future opponents and their is a reason why. They don't want to give anyone more motivation than normal to kick their butt.
And, the on court drama that he displayed in Australia needs to be controled unless he is the 1 in 1,000 that plays better when angry like McEnroe.
My advice to Jersey is "shut and play, and be nice and respectful to your elders".
