If I have orthopedic or other related sports injuries, make millions of dollars a year and I want a second opinion, I'm going to Dr. James Andrew not some doctor in Spain. But that's just me.
What if the doctor in Spain is someone who has successfully treated you in the past? Faverani played eight seasons in Spain. It's shouldn't be surprising if he wanted to talk to a doctor with whom he had a long-standing relationship and a level of personal trust.
Of course, maybe it could be a secret physical to assess whether a Spanish team is willing to sign Fav if he is waived, which could lead to him being willing to accept a buyout.
