Beane has got to be let go.  Payroll is his excuse and he is lucky for that. Who hires there best man for manager? Only Beane would do that looking for a puppet so he could be the one in charge. Beane has made way more bad moves then good in his tenure and moneyball does not work. 

Crosby: cleary not a mlb caliber player: Beane sees himself in crosby and keeps him for that reason. 

"but he developed the big 3" : no the coliseum is a pitchers park for sure so he has gotten lucky with a few guys

bad trades: Harden, Pena, harang, hudson, are just a few of the many terrible trades he has done

bad signings: Rhodes, Kendall, Piazza, Sweeney, Chavez, just a few of the terrible Signings

letting everybody go: payroll is not a good enough of excuse for not  keep star players.  Teams with similar payroll dont ALWAYS trade good players.

MONEYBALL: DOES NOT WORK- too many bad moves folks 

it does not make you a better fan to just always think positively.  Im not saying always be 'Negativity Nancy" but come on face the facts.
