The idea that Basketball and Hockey are the two weakest products for sports cards (of the major 4) isnt all that true. There's actually a lot of demand for both! Oh sure you know the big names in both sports being great for return on sales! But While you might think Hockey is world wide popular, it's not nearly as popular as Basketball.
I sell a lot of basketball and hockey on ebay and I find myself sending most of my Hockey to Canada, USA and a little bit in Europe. Basketball on the other hand... Canada, USA, Europe Australia and even some of the Asian countries like Korea, Taiwan and Japan! Personally I think Basketball is far more popular than Hockey. However, Hockey is certainly on the rise very quickly! The products Hockey has released in the past few months have been top notch and no matter what anyone says, Hockey still has the most colorful and dirty patches out there!
