NBC has the NHL, ESPN/TNT have the NBA, ESPN/CBS have Major League Lacrosse. I doubt I'll even notice this channel exists when it does.
They'll have NASCAR, MLB, UFC, several NCAA conferences and the World Cup. Plus, with a national network they can include it in bids for new rights since they won't be limited to clearance on FSN and affiliated stations for national programming and events:
-- Affiliates owned by 3rd parties like MSG+ and Root wanting to do their own thing at times
-- Former affiliates like CSN dropping FSN's national programming, losing clearance in many major markets like Philly, Boston, Baltimore, DC, Chicago and San Francisco.
-- Local major league teams get priority so national sporting events like UEFA and College Football games are pre-empted on a regular basis. This was especially of note in NYC prior to the launch of YES and SNY when FSN's national programming like the Best Damn Sports Show and TNA iMPACT! only got cleared whenever the Islanders, Devils, Nets and Mets weren't playing.
