Its rough for NBC right now. Their numbers aren't that great and they used to be a sitcom powerhouse, Must See TV Thursdays used to mean something for decades.

Take a look at all the pilots they picked up, it's like two possibly three that will be worth it and even then those might not get the following that P&R and Community have.

If Harmmon is bringing back fans and bringing in numbers which in turn brings in advertisers why not? They need him right now, they know it and he knows it.
