No. East Lot parking will be substantially higher than it has been historically. The outdoor practice field behind Anderson had previously been used as “Wildcat Alley” while the outdoor field behind baseball was not used a ton.
You saying “available lots” is just the “premium lots” right next to the stadium. There are plenty of other options throughout campus, in downtown Evanston, etc. Plus whatever NU can do to push people to public transportation, which isn’t really an option at the vast majority of stadiums.
Long story short: NU fans are going to have to get used to how it works at pretty much any other decent-sized college stadium in the country. You’re gonna have to walk or you’re gonna have to pay a pretty penny.
EDIT: If you really want to nerd out on it, then there’s a full-on Traffic Plan available on the Evanston website. It’s geared toward the concerts, but determines that there are >6,700 spots available in the West Lot, East Lot, on campus, and at 3 public lots in Evanston before even considering Canal Shores.
EDIT #2: If you really really want, then you can even read the draft traffic management plan:
