Comparing a CFL stadium to an NFL one or an NHL arena is a little unfair. The CFL is my favorite pro league, but it is a minor sports league in the overall scheme of things. I have read on forums that steel bleacher construction is horrible, but new NCAA stadiums and soccer-only venues like BMO Field and Saputo Stadium are built that way, so why not for the CFL? IMO, a new CFL stadium doesn't need to be any better than a new NCAA stadium.
Gerald J Ford Stadium for the Southern Methodist University Mustangs (NCAA Div 1-A)
built in 2000 for $42 million and seats 32,000
Bright House Networks Stadium for University of Central Florida Knights (NCAA Div 1-A)
built in 2007 for $54 million and seats 45,000
If either of these were CFL stadiums, they sure wouldn't be the worst in the league. And they'd definitely be the nicest stadium ever built east of Montreal.
So what's wrong with thinking small? Doesn't the 2007 Saskatchewan season prove that all you really need is a stadium filled with fans to make money in the CFL? A stadium with good sightlines, enough legroom, that isn't falling down or a firetrap, has the right number of seats and enough bathrooms/concessions is all I would ask for.
If you can play football and make money in a $50 million dollar stadium, why spend $100 million or more especially considering it sits empty for 355 days every year?
