This is why it’s hard to get excited about the Houston Rockets.

Over the past three seasons, Tracy McGrady has missed an average of 21 games due to injury. Now the AP is reporting that T-Mac is going to miss three weeks as he rehabs his sore left knee.

Here’s what I wrote in our season preview of the Rockets:

If T-Mac, Yao Ming and Ron Artest can all play 75+ games and are healthy for the playoffs, this team will be very competitive. But as history has shown us, that is a HUGE “if.” Yao hasn’t played more than 57 games in any of the last three seasons and McGrady is averaging 61 games played over the same span. So the Rockets can’t really hope that the duo will stay healthy, they just have to hope that whatever injuries T-Mac and Yao do sustain aren’t of the season-ending variety.

Hey, at least this isn’t a season-ending injury.
