I'd say its more quality than uniqueness (unless we consider quality to be a unique feature now, which is more of a sad commentary on the current status of sports writing on the internet).
My issue is, that while the two cities they picked are very convenient for my fandom, what do I really not know about the Blue Jays/Blackhawks/Raptors that would compel me to pay $50 per year? And then you get further down the road into teams like TFC (where the writers are just general sports guys instead of picking from a rather well-established base of long-time soccer writers in the GTA), and I'm fairly confident I know far more about the sport/team than they do.
The one thing I would potentially pay for is access. Although it is a ghost-written, extremely biased website, I would say the Players Tribune is my favourite sports journalism (maybe 'journalism' is better) site right now, because it provides content that I have zero chance of re-creating myself from watching the games/events.
