Not sure what you mean by "all the sports channels", and you probably won't like my suggestions anyway if your accustomed to unlimited everything but I'm going to tell you anyway.
I've watched both road football games on regular old free YouTube, NOT the paid for YouTube TV Live. The SC game feed got shut off once so I went back to the main menu and selected another feed for the game and watched the rest of it from another of 4 feeds that I saw. I tailgated but my neighbor said both home games were on there free. I watch all road games for baseball on there too. I don't do basketball so have no clue if those are on there or not. ESPN Unlimited is probably easiest @ $29.99 or there's ESPN+FOX ONE for $39.99 I just found out Monday that I can piggy back off my kids Disney+/ESPN/Hulu bundle so I tried their log in and it worked but not sure how long before Disney shuts me out for that. HULU LIve is supposedly going away anyway and going to be absorbed into the Disney family if it already hasn't , it won't be available as having HULU only by itself anymore but that Disney bundle they have is only $39.99/mo
Have you tried to see what can you get w/ an antenna where you live? I get all of the regular feeds in Starkville (NBC, CBS, ABC, FOX, that carry games but have also noticed that THE CW has a lot of games now too on there.
