Wertheim is to journalism as a bicycle is to a fish.
He frequently contradicts himself. Look at his view of people holding the #1 ranking without holding a slam title over the course of 3 successive years. When Davenport did it in 2001, it was an outrage. Yet when Agassi was on the verge of doing it in 2002, it would "validate the tour". Then, when Clijsters did it in 2003, it was "an embarassment". Double standard much?
To the apparent surprise of most tennis writers, there are more than just these 2 tournaments on the tour. And as such, the players set their schedules accordingly to balance matchplay, rest, surfaces, etc. Even then, every top player was entered in either IW or Miami, with almost every player in both. Only the Williamses were not scheduled for IW, and only Henin and Davenport were not scheduled for Miami. Those are deep fields. Thus, the problem is not one of player "scheduling", and as such, making these events "mandatory" would not have helped.
The problem was, plain and simple, injuries. And these aren't scheduled. Mauresmo and Rubin couldn't have said back in early February that they wouldn't be healed in time for IW or Miami. Clijsters and Myskina couldn't have said that they would get injured at IW. So it's nonsense to expect other players to have to cover for them, as their absences from these events came at the last minute. The only "moral obligation" a healthy top player has is to honor her commitments. In the case of Henin and Davenport, these included AI and Charleston, BOTH of which would have to be jettisoned to take a late entry into Miami. And they would be running the risk of injury themselves.
And yet, in direct contrast to basic logic, many writers are calling for the WTA to "do" something. "Do" what, exactly? Pass a new rule banning injuries? Yes, let's legislate good health. Or should they just force players to play? Myskina probably could have played Miami if she was forced to. And she even more probably could have done a more serious injury to herself, necessitating the absence of more than a few weeks. Let's see... player climbs into top 5, becomes darkhorse contender for slams and Olympic medal, forced to miss those events as career is interrupted by injury incurred/aggravated by mandated play... how many millions could a good lawyer get for that? But then, it's not the writers' money they're gambling.
