Expanding Cajun Field is the absolute stupidest idea I've ever heard of.
Please tell me I'm not the only one here!
If anything we should reduce capacity by 10,000.
A good example to look at is Major League Soccer, whose teams average about 18,000 per game just like UL has for the past few years. Instead of building 50,000 seat stadiums hoping for a miracle to happen they have built really nice 22-25,000 seat stadiums. This creates a much more intimate setting. When you have 20,000 people in a 20,000 seat stadium the atmosphere is great. When you have 20,000 people in a 45,000 seat stadium you have a lot of empty seats and not a lot of atmosphere. Also it creates big demand for tickets which means you get tons more season ticket holders. This means more people paying for tickets for an entire season which means more tickets being purchased and a steadier source of income. And if we start to sell out every game consistently that's when we slowly expand. If we expand too quickly we lose season ticket holders because there is no need to buy them anymore when you can just walk up and buy them.
This is why the MLS team in Toronto won't expand their 21,000 seat stadium despite the fact they have sold out every game since they started playing.
This is also why Seattle's MLS team won't sell more than 28,000 tickets in the NFL stadium they play in even though they also sell out every game.
This is also why MLB teams have built smaller stadiums. Instead of spending $800 Million on huge stadiums they spent that money on making fewer seats more valuable by building nicer stadiums with intimate atmospheres.
Small, first-class facilities will create a high demand for seats. Spend that money making Cajun Field nicer and not bigger. There are a million things we need to improve! We have enough empty seats as it is.
