All indications (from the post-game and Brannen radio show) seem to be that Brannen is going to double down. Brannen's opinion seems to be that the problems are because he hasn't installed his culture strongly enough. His given players too much leeway, he has let culture slide in favor of winning now.
Coaches (Brannen being no exception) tend to have big egos. He doesn't think he is the problem, the players are the problem. If he has made mistakes it's because he has been too lenient.
If it works and we turn things around great. If not, it probably burns things down quickly, which is also good as we don't want to keep a bad coach around longer than needed.
The rest of the season and early post-season will tell us a lot. There are a lot of indications that there are issues in the locker room. It's either players or Brannen, but there are definitely problems. Either Brannen fixes it, or there is an exodus and Brannen's coaching career here will come to a quick end.
