Ben Roethlisberger -- Doomed by Billy Joel?
After Ben Roethlisberger's crappy performance last night ... everyone's been asking the same question -- should he have stayed in Tuesday night and watched game film instead of boozing past midnight??
As TMZ first reported -- Big Ben dropped $1,000 at a Dallas area piano bar ... drinking rum and Diet Cokes with some teammates past midnight ... while karaoking along with the Billy Joel classic "Piano Man."
