They should have put $50m into RFK instead of $600m+ into the new stadium.
Not a baseball fan, I take it?

RFK is a cookie cutter. It is therefore obsolete and must be done away with. Renovating old stadiums like this is, by definition, not cost effective; building new parks is simply more efficient.
Plus, RFK is an ugly piece of shit anyway.
New ballparks are an objective good. All teams should have one. The sooner we sweep away the last of the cookie cutters, the better!
