Re: coaching Halep from behind the keyboard
At the net it's all about confidence. You may not consider yourself to be a net player (I'm not speaking for Halep -- she does a pretty good job there, though I've seen lapses, too), but you find yourself, often on tough points, at the net, where the confidence is needed when you're there to make all kinds of shots. There'll be no confidence without match-toughness, which might well entail forcing the issue, at net, at times. I find it does for me in my club play.
