How many ad slots does $185k buy on Hannibal?
Other way around.
This isn't my forte, but let's play a game.

These are the average upfront sales for the 2014-15 season. Let's lowball and pick a comparative show given its ratings this season. How about... The Originals? Sure. That went for about $39,000 per 30 second spot. Dramas run at about 42 minutes, which means 18 minutes of ads. Some of those are promos. Let's low ball and say there are 15 minutes of actual ads.
That's about $1,170,000 (this is not an exact science, this is not my area of expertise, and there might be other costs I'm not aware of). Now, take away $185,000 from that. That's $985,000, or ad revenue you'd make per episode (again, I dunno! Maybe this is wrong!).
While, yes, NBC could do better, that's a pretty healthy stream of profit for a show that airs in the summer that's not really taking a timeslot from anything else. So, like, what?
I think syndication is where you really make the big bucks in television, and I doubt NBC with the 185k investment per an episode were getting a lot on the backend.
I think most television is profitable on the major networks, and just being a little profitable is not enough for them.
NBC would get nothing on the backend of Hannibal anyway, just like they'll get nothing on the backend of The Blacklist*, or ABC will get nothing from Modern Family or Fox will get nothing from Gotham. While corporate profits are nice, the networks themselves make their money in ad revenue. That's their only source of income. We haven't gotten to a place (yet) where networks are just farms for their own content
unless you count ABC.
Also, NBC seems to give less of a shit compared to other networks about buying from outside studios.
