Personally I think this is all making the Cavs look terrible. I don't believe that they didn't request all the medical paperwork on IT. I can't believe that the Cavs doctors are just so incredibly better than the Celts doctors that recommended rest and rehab. I don't believe IT's hip has gone down hill. 
It's all BS and show and Ainge can't let himself get pushed around like this.
Its one thing to read a medical report, it's another thing to actually examine a patient. People understand that, right? It's not uncommon for a patient to get a 2nd opinion that isn't in line with the initial prognosis/course of action. Some doctors have made an entire career off of this. Essentially, this is what's happening. 
I'm not sure why people aren't getting that.
The Celts doctors recommended rest and rehab for the summer. The Cavs doctors would have to have come to a conclusion that is just totally different from that. I don't believe it. I think the Cavs know IT will be back at some point. I think the Celts kept them informed. 
Notice the Cavs didn't jump up and down about getting IT. They weren't like "Oh we're so happy to get him!"  Now all of a sudden it's some huge problem? 
What is this? Do they want IT or not? If you don't want IT we'll keep him. 
If you don't want him then this shouldn't even matter.
The Cavs are playing and they're gonna get played. My GM is better than theirs.
