I don't think any of us 'know' that Price will be okay. All I've said is that I'm comfortable with what I'm hearing from Price and Farrell, which leaves me optimistic about him returning sooner rather than later. I fully understand that there's a good chance that he won't be ready to throw when they re-evaluate in 10 days, but nor do I think he will be out for 1/2 the season or more.
As far as Price misinterpreting what Dr. Andrews said, I believe that if Price (or Farrell) were saying things that were not correct, someone would correct him privately. Maybe Dr. Andrews would contact Price himself, or the team doctors, who would certainly have the correct diagnosis given to them from Dr. Andrews himself, would correct Price.
