ESPN and NBC share the broadcast rights to the US Open. On Friday night, during an evening replay of the day's action, ESPN2 re-aired some of NBC's coverage from the late afternoon window. That coverage included this promo for Game 2 of the Stanley Cup Finals airing on NBC Sports Network tonight.
So yes, as a function of sharing broadcast rights, ESPN ran a graphic advertising hockey on NBC Sports Network. I think we all know the joke that's coming...
This is the most ESPN has cared about hockey in years!
