Because they are idiots? Why else would you not sell as much of your product as you can? Only other reason would be if the cost of hiring a bigger stadium was more than the anticipated extra ticket sales.
Perth wildcats moved from the 2500 capacity challenge stadium to our new 12500 Perth arena.so far they have had two 10k+ crowds and sold 6000 season memberships. You'd best give them a ring and let them know they should have stayed in their smaller home and kept demand high!
Geeze you are an idiot. I never said teams shouldn't move to bigger stadiums and grow their product. But there are many examples when a team may decide to limit supply as a strategy. You claimed it hasn't been done before. I could list heaps of examples but gave you a valid recent example of the strategy.
The reason they did it was to encourage membership (guarrantee your seat), promote hype, improve atmosphere (give people a good experience at Parramatta during a sold out derby, theyre more likely to come back).
The Storm's recent prelims at AAMI instead of ETIHAD is another recent example
It's a strategy that has its role whether you like it or not.
