Well the argument was actually in the article we are discussing here, which says it is a bad financial investment. I actually believe that even on a back of the envelope calculation it's hard to imagine how one can come up with this being a net positive. Let's argue that a stadium brings in 1M visitors a year (which is a high number) . If a stadium costs 1B then the city (through taxes etc) needs to make around 100 per person for it to be a good investment (10% return). And we haven't even considered the costs of externalities, like large traffic jams during games, cleanup etc.. I find it difficult to imagine that this works.
