Also, look at these teams early results for the fall and realize that last years rankings are mostly accurate. Last years season only ended in August.
While I do agree that it may be early and not a lot of data yet you also need to take into accounnt rosters change and skill level changes. You had empire beat a top 50 team last weekend than lose to a team ranked 86th today. The reasons ratings start fresh every fall is because of roster changes, last year rankings are no longer accurate. By the end of fall rankings should truly represent what teams look like. Give it two more weeks.
