The insights here are courtesy of Mark Dent at The Brew House. His entire analysis can be found here. As someone not particularly into sports, I still found Dent’s detective work interesting.
I came across his post while in the process of unraveling the timetable for the events starting with Zod’s ultimatum. I don’t know whether the game is meant to be a live one diegetically, however, even a rebroadcasted game would not represent a story-breaking plot-hole. Notable games are rebroadcast on select channels, and Dent concludes that this was a “hell of a game” perhaps worthy of rebroadcast. The fact that CNN’s feed is shown when the breaking news interrupts is not an issue. Branding from other channels is permissibly and often carried over for breaking news, particularly with exclusive footage.
Enough apologetics, on to Dent’s conclusion….
