For free? Good luck. You do have a low-cost alternative if you're cutting the cord, however:
Sling TV is a low-cost alternative to cable or satellite that comes in over your internet connection. Sling offers AMC's "live" (current) programming, delayed a minute or two for buffering. Plus they also offer a limited amount of On Demand programming. In the case of AMC, Better Call Saul and both Walking Dead series have at least 2 episodes available to watch On Demand.
You can watch Sling on Amazon Fire TV, Chromecast, Roku, most phones and tablets, a number of WebOS devices such as Smart TVs and Blu-Ray players, and even your PC. It costs $19.99/month for the basic package, which includes ESPN, ESPN2, TNT, TBS, AMC, HGTV, Disney Channel, History Channel, Vice, Cartoon Network/Adult Swim, CNN, and others. You can add packages (there is a sports package that includes most of the ESPN networks, plus SEC Netowrk) for $5/mo, or $15/mo for HBO.
