I think that is an overstatement. From what I remember, Danny said that the bone spurs were bigger than they though, however, he maintained that it was still a minor surgery.
I'm pretty sure Danny said something awfully similar to my post.
I think the point is though that no matter how you want to characterize the off season surgery, he had recovered from that. He played fine from the beginning of the season until the 12/28 GSW game where he HE'ed his knee. He wasn't landing on one leg, he wasn't looking down at his know when he ran, he was just playing and moving around just fine.
What ever is going on is new since the GSW HE Knee incident. Unless the HE Knee brought back bone spurs overnight which I am not a doctor but doesn't seem too likely, there is something else going on.
Hang on KG, just 20 or so more games and then hopefully 20 or so playoff games.
