I don't understand the point of bringing up Dunn.
They are similar players. Agreed. (Though it should be mentioned that Howard has clearly had the better career. Former MVP and will go down as one of the greatest players in our franchise's history.).
And Dunn makes less money. Ok.
So if we had Dunn we would some how be a better team? Even though Howard's contract has not restricted our spending in anyway? This notion that we would be a better team if we had Dunn is just ridiculous moneyball nonsense.
