We may certainly do worse - that’s how football works

Generally the rule of predictions is that with no other information the best guess is that things will be roughly the same from a single time increment to the next.
With NFL records somebody has to be worse for somebody else to be better.
I think we will be better personally but it beats the old days when prognosticators would pick 20 or more teams to be above .500
