I think other than cowboys stadium, it’s looking like most newer stadiums are at around 60,000ish or so. That allows lots of room for the money making luxury boxes.
I am really hoping they build a stadium similar to Lucas Oil in Indy. Fully retractable roof. This will give the Bills a great advantage too— they can eye the weather and decide what they want to do heading into a bad weather game. To me, keeping out rain and gusting wind is important. Snow and cold is totally fine.
