looking at this purely as NBCSN being "weak" is the wrong way. Comcast is looking at their entire portfolio. Between all the channels they have (USA, Syfy, E!, Bravo, Oxygen, Olympics Network, Golf, NBCSN) think about how much original content is there vs. what is just re-runs
The market for reruns is drying up because people are binging that stuff on streaming now. I mean, they are streaming everything these days, but the draw remaining is live events and reality programming. Most new scripted drama is going to streaming, and reruns are on streaming
So, yeah, NBCSN is weak but honestly so is the rest of the overall lineup. And if you're going to right-size the number of networks and spread the content around, it makes sense to get rid of NBCSN which was in the fewest homes out of the rest of the non-niche networks. USA is in the most homes out of any of these. I don't see NBC dumping any content. Some of it will end up on Peacock, sure, but most of the destination viewing will be on NBC or USA. The point is to beef up USA, not just cut dead weight
