Two points. First, do they not have fax machines in China? What the heck is the holdup on this paperwork? Can't they cyber steal the plans for a fax machine from some American company and get some paper work done?
Secondly, there are talented 7ft'ers out there that can contribute. Maybe they aren't stars who can do it all but there are the Stiemsmas out there who can do one or two things well and contribute for short minutes. I'd guess there are hundreds of guys out there who, if given the opportunity and the right circumstances, could be very good players in the NBA.
