Actually the A's seem to be trying to it, at least their public stance is, w/ private monies. That's what the Giants did. They paid off their debt last year after only 16 years. Of course their ownership wanted to & produced winning teams.Oakland is still on the hook for 83 m $$ for getting the Raiders back.
Again my point is that 81 events vs 10 events should bring in far more $$ in taxes, concessions, parking, etc. plus the added tax dollars from surrounding businesses based on the number of games that bring people into the area.
I' m long time BILLS fan, but the number of baseball games far outnumbers football games.
