Steroids aside, ARod was mostly booed unfairly. The guy winning MVPs and driving in 125 supposedly wasn't clutch and supposedly wasn't earning his money.
For some reason, the 4-5-6 overpaid slobs on the 2014 Yankees are not getting booed.
Maybe it's all anticlimactic after ARod. Maybe the fans are just disinterested in general.
I think a quiet stadium might be worse than an angry stadium.
