I'm not sure I agree. Points are only relevant to the season in question, comparing to other seasons is pointless as it doesn't take the relative strength of the rest of the league in any given season into account. Someone may well finish 7th with 80 odd points, they won't be unlucky, they will finish where they deserve to, in the same way as Peterborough going down on 53 points wasn't unlucky.
Reminds me of when people claimed we did better in our second Prem season because we got more points than the first even though we finished lower in the table.
