ESPN has used it's app to air more & more sports either exclusively or simulcast with either ABC or an ESPN channel so yes I firmly believe it can. I've LONG believed that
In fact, they can take ESPNNEWS & make it a streaming only channel available for free (Like CBS Sports HQ is) or on streaming services like Hulu, YouTube TV, Sling, etc RIGHT NOW as all it is is basically SportsCenter all day (In fact, they can even use that as a name with the moniker being SportsCenter 24 Hours A Day) just as they call SportsCenter on ESPN Radio SportsCenter All Night
