I guess Manu's problem wasn't that Parker didn't pass him the ball and Pop didn't call enough plays for him
This injury is pretty horrible timing. If it's serious at all, Manu will have to sit out until the playoffs begin. At that point, he'll have to attempt to find his groove in the middle of the Spurs trying to survive the first round.
Hopefully Ginobili can return for the last few games of the season to get back into rhythm. But yeah, most important thing is for Manu to be healthy in the playoffs. If he's not healthy, there is no chance of a championship.
