If you build it, will they win?

I should probably make a big spreadsheet and run correlations to respond to this, but I’ll leave that to someone else with more free time today.

I did, however, do a study for Baseball Between the Numbers that looked at MLB team performance before/after moving into a new stadium, in which I concluded that a new ballpark is worth, on average, 5.5 wins a year to a ballclub. I further noted: “a $500 million stadium is an awfully expensive way to pick up five and a half games in the standings.” Unless, of course, somebody else is paying for it – as is the case with the Arizona Cardinals.
