Why are the Hawks allowed to have their local feed? FSW being cheap?
Comcast owns NBC. Comcast sportsnet is the local feed for Chicago, San Jose, the Washington Capitals, and the Flyers. That is part of the reason that we always get their local broadcast/teams on NBC. They already work for comcast.
Same reason you never see ANY Fox Sports teams or casters doing national games on NBC. It's not Fox being cheap, it's just NBC using the feeds and teams they already have hired for CSN broadcasts.
