Eagles were crap last year becasue Kerr & Glass were injured, Embley was out of form, Cox was carrying an injury and Lynch was out of favour (palying WAFL). Thats 5 prem players and unless im incorect they've all been AA too (maybe not lynch?)
Also their players like Masten, Ebert, S. Selwood, Rosa, Nikoski & Butler (who until this year havent shown a great deal and many have been quick to write off) have improved significantly.
These two factors combined with a well drilled press are the reasons they are looking the goods.
