A cloud of uncertainty currently hangs over the 2012-13 NHL season as the league and its players continue negotiations toward a new collective bargaining agreement.  Although it's uncertain if the season will start on time, the league has still managed to plan out its nationally televised games for the coming year.  The Sabres will be seen around the country 15 times if there's a full season.  That's up from last year's total of 11.  Most of the games will air on NBC Sports Network, but Buffalo does have one on NBC.  They'll play at Washington on St. Patrick's Day, March 17, 2013, at 7:30PM.
