If a shared stadium = shared costs, then you have to be in favor of it. I don't care IF UB draws 3 fans, the cost share would be a constant, and would help.
Whatever happens in the future, the WNY taxpayers cannot, and likely will not support any funding/bond issues to finance whatever may be proposed, so every option has to be investigated.
Maybe a future design would even be attractive to the Bison's?
