As much as it pains me I feel like Geelong 2011 should come into discussions tbh, not because of W/L record but because of who they beat which was Collingwood who more than likely would've gone the whole season without a loss themselves and beaten Essendon's record. Literally the only team we lost to was Geelong throughout the year. Honestly that 2011 team we had was insane, and it wasn't as though we were shit in the grand final, Geelong were just unbelievable.
