I recently signed up for a service that cloaks my IP so it looks like I'm in Europe.
I've been able to watch every playoff game on my mlb.tv account because of this.
I've also been able to sign up for NFL gamepass (a streaming service sold outside the US) and watch any football game I want on a 2-3 minute delay.
Netflix also thinks I'm in Europe so my selection of movies is actually good.
Bear in mind that I still have to pay for these other services (mlb.tv, gamepass, Netflix), but this is way cheaper than going to a bar and starting a tab to watch the Os/Redskins. And being in Chicago, that's basically my only option for watching most Redskins games and almost every regular season Orioles game.
EDIT: I also own an gen 2 AppleTV that I Jailbroke so I could watch gamepass on it. Basically that means that I can watch any of this stuff on my TV, and don't have to watch on my computer.
