Yes, I believe people would. I pay for the NFL's GamePass, which is similar (without the live streaming) and costs $100 for about 4 months worth of entertainment.
I pay for single sport subscriptions (UFC and MotoGP). I think they work out to about $10/mo for each. I don't follow the major US ball sports, but it seems like they're a bigger deal with more games than you can watch. Spending $25 doesn't seem outrageous, of you're a fan.
MLB for one team works out to be around $.60/game... I watch everything on delay, which living in a different city than my team means I can pretty much just watch baseball at work for 1/2 the year. I just wish google would let me block sports scores on news. Just like who died on game of thrones, it's not news I care to see fed to me, I'll go find out the score if I need it.
