its predictable i guess, when i play defenders i know when they want to attack most of the time, plus racket technology i simply redirect the ball and win the point, when defenders attack they leave them selves wide open alot

+10.

Since the poly ball, I have seen lots defensive players trying to attack more and more simply because their spins don't make the difference anymore and also they are fed up receiving hit bullets from the attackers who have no more difficulties, even on low balls.

At a relatively good level (not a world class level of course), the regularity for a defensive player should remain on defensive strokes and he doesn't need to be able to be as good as an attacker in pure offensive rallies simply because he should attack maximum 3 or 4 times in a game.

But these attacks have to be carefully prepared and done in the key moments of  game.

The knowledge of his pimples or anti rubbers is much more crucial than the knowledge of the inverted one of course. In training session, the defender should learn and practice ball placement and way of using his material in order to get these vital 3 or 4 attacking points in the game which lead to a 11-9 instead of a 9-11....

If he attacks too much and on non enough prepared balls, the opponent will not be surprised and will easily block him and put him out of position. Than the frustration will come and the strength of the defensive player (his regularity) will become his weakness because he is probably less regular than the usual attacker at this game.

......Of course, if you are JSH, or Gionis, players with a forehand as good as the one of a world level attacker...things are a little bit different.
