in all fairness about the Buffalo stadium...

It is 47 years old.

And also this from their Wikipedia page:
The size of the field at New Era Field is specifically designed for National Football League dimensions and sight lines, making it extremely difficult for other outdoor sporting events such as soccer, baseball, track and field, or rugby to be held there. None of any significance have ever been held at the stadium.

It would make perfect sense to replace it in the next several years.
