Very, very unlikely he comes out if that's the case. His rehab is supposedly going well. People freak out over hip injuries because everyone thinks the most obvious case - Bo Jackson - and assumes the worst. He wasn't a super shifty guy - he's merely a guy who has incredible pocket presence, strong decision making and laser touch accuracy. Those things aren't going to be taken away from a hip.
If every specialist Ross throws at this kid says he's okay, I think you easily give up a 1 for him.
I just don't see any way he falls out of the 1st if he cames out. That being said, I don't think he does. I know he's got the insurance policy out there, but Tua's a competitor. He's not interested in being drafted 5th round, picking up a $10 million dollar check from Lloyds of London, and then fizzling out after 3 years. He wants to be in the best situation he possibly can be in.
