The question is not why Littrell should be terminated, it is why should he be terminated mid-season.
I would be more than surprised if Littrell is fired before season end.
Again, the question is what would NT gain by terminated Littrell now. IMO, nothing; the team is not going to magically get better.
It is my opinion that NT has a better chance of winning some games this year without an added drama of firing a head coach because of his record. If Seph was running an outlaw program or had personal conduct issues, it would be justified.
Your above justifications relate to losing and the odds are not going to improve with another distraction for this team.
Yet even when other teams do well there are those you feel the need to take jabs at them. People on here joked about the hires at ULM and even with the crap show we put on we still here about how certain other coaches are not good enough for us or too old.
