It really is dumb to compare those two. Sling is basically Dish..who's revenue was what? 15 BILLION in 2016 and all of the sudden people are coming out with claims like "Yeah Viva is complete BS compared to it" - Oh yeah..why do you think that is? Maybe because Viva started with, well, nothing and Sling had billions (sorry, my mistake on my last post about millions) backing it.
As for football, not sure if the person knows but the channels that do offer football are usually the most expensive to offer due to licensing costs. So maybe it will come in a stand alone package later on that you could pick as an extra, I hope it does but man, really. I pay €9/mo for those channels alone (2 channels only).
