Thing is, streaming is the future. Sports viewership is declining precisely because it continue to hold to the old cable model and refuses to move into the modern day. Cable costs more and more due to sports, and cutting the cord is becoming more popular. As that happens, more cordcutter live TV services are becoming places where there are no sports (andd in many cases people are moving to illegal IPTV services that provide no Nielsen info or money to the pockets of the channels). That puts more pressure on the sports providers since their current model is based on the masses paying a little each even if they don't watch rather than the people who do watch paying for the sports directly.
They pay extra to show it in those bars or risk losing everything to a lawsuit. Bars will show what the patrons are interested in and something like every NCAA game on ESPN+ would possibly bring in more money direct to ESPN than counting on the cable money. The reason they don't do it now is because ESPN+ does not include the stuff on the live ESPN Networks if you aren't already subscribed to cable that carries ESPN. So ESPN+ right now is an extra cost. I doubt ESPN live networks all die, but I can tell you that they will be cutting back at some point if they don't move to a more streaming approach. I could see ESPN going more regional maybe but I feel the move to more streaming is coming. And think about it.
You are looking at it from an Alabama fan perspective, where all of your games except maybe one are on SECN, ESPN, CBS, etc. The vast majority of NCAA football fans would already benefit from ESPN+ as their team is rarely on the big networks but might already be on ESPN+. Streaming is the savior of sports broadcasting in the long run.
