Hi Howard, happy to read you in Caroline Topic, always very smart post
as for the comparison with Mc Hale, it's true one is more successful than the other but one is more talented too(caro). It takes more time to set a more complicated game and have results with it. Caroline is more an "offensive" player who likes to attack with powerful shots. McHale game is more mature, safer too. She can bring back a lot of balls. I think her serve should be improved cause it is not normal to not have total control of your serve because of your toss. She has to make it shorter and more simple. Look at Federer one, it is pure model to copy.
she must improve it to make big things.
