I used to be into that, but Kodi started to become a pain after all the streamer quality got low, I had to pay for RealDebrid just to get a decent stream, I never quite got sports streaming to work with any of the apps, and the Firestick itself got ungodly slow over time.
I have PCs hooked up to all my TVs, so if I can’t find something on my streamers I can just open up my browser and google a solution.
Luckily between Amazon and ESPN+ I can meet most of my sportsball needs. For those not on the apps, there are websites that can assist.
