Yeah, clearly this is the first time TV stations have dealt with multiple games in the same region so no one's prepared for this crazy scenario.
There's at most 2 or 3 dates on which Devils/RB have games on the same day in a season, it is not rocket science to consider one more factor and make it possible for people to walk the 15 minutes between arenas. Clearly not a priority for MLS, but it is far from hard/impossible.
You're pretty silly. There's shittons of logistics involved in doing anything like this and your dismissiveness belies that you perhaps have never personally managed or developed anything of much complexity (don't conflate hard with impossible tho, impossible is nothing). Also - the assumption that there is enough crossover demand between the devils and rbny is a bit naive - I personally hate the devils. fuck the devils.
Happy holidays!
