Well, to start:
PNG-W hasn't really faced a tough team yet, yet their biggest win is only by 2 touchdowns.
Also, Ned-B beat Lum-W, yet you have Lum-W ranked higher? They only beat a weak Bmt Warrior team by one point. Not sure how Neb-B fared against the Warrior team this weekend, but I'm betting it's by more than a point.
Also, Ned-W - same scenario as PNG-W, haven't faced a tough team, biggest win is by 7 points.
These are power rankings, correct?
