At this time no one knows how the heavily hyped new football league, a joint venture between Vince McMahon's WWF and NBC, will fare with fans, viewers and sportswriters (see 'XFL Hits the Field').  Diamond listed the XFL cards in the 'Non-Sports ' portion of the Trading Cards Section in Previews, a small thing perhaps, but indicative of the attitudes of many toward the new league.  It's also worth noting that ICv2 (which does not cover sports) is covering the XFL.  But whatever you think about the XFL, given the state of the current market for licensed sports cards, it's hard to argue with the XFL's decision to go with just one licensee.  There are simply too many companies making too many different 'brands' of sports cards for all the major professional sports leagues in the U.S.  Most collectors can't even keep track of all the different card issues in their favorite sport, much less collect them.  It may not be 'your father's football league,' but the XFL's licensing policy, like many of its rules, hearkens back to the glory days of the NFL and MLB when Topps was the only trading card game in town.
