Even if Riley would have been 3-1 at this point (highly doubtful, but just hypothetically), he would still be the wrong guy for the job, because we have seen how he coaches and how he goes about his business. We saw Riley's ceiling, and it was soft mediocrity. Being winless this season sucks but the ceiling is much, much higher.
If Riley were still here, the players might be more comfortable with the schemes, but those schemes sucked donkey balls anyhow, and we would still have turnovers and stupid mistakes, so I can't imagine it being any better than it is now.
