Similar injury is not the same injury. Few players have returned from Collins injury. Many more have returned from Finley's injury. However, its not a lock every team Doc will clear him.
So his interest in other teams COULD be an indication that he wants to leave, or it might be an indication he MAY HAVE TO leave, in order to continue playing. Plus, either way it never hurts to have more than one suitor.
