Do you realize ECRL is just finishing its second season (the latter in which fewer games were played due to covid)? They have no history. And, how many real games did ECRL play against DPL? I am going to guess close to zero.
Those rankings are meaningless when many teams change rosters significantly year after year. And, I assume your dates are off so I won't even argue that. Ask a college coach what DPL is and they will tell you they have no idea.
I would bet that DPL will not exist in a couple of years. They are B teams to the GA clubs, yet you place them ahead of GA.
