Hardly cruel, they never even know. They're sleeping when the footballs arrive, when they wake up the event is gone. No harm, no foul.The next event will also have an awesome reward. In fact, it will seem like we get almost no downtime until there's something starting again.
As for more footballs, I don't ever recall getting an extra daily award/daily special at the end. The last few hours are so that everybody can finish up the questline and spend their event currency. That would be after midnight eastern, that would be cruel to give people who are sleeping footballs that they can't use when they get up in the morning.
As we will have one more DS, a level 1 Watchfire, I'm encouraged we'll also see one more drop of daily Footballs, but only time will tell.
