Yeah I doubt it'll be crazy and Syracuse has the benefit as far as noise of being in a dome.
But if Cal beat FSU this week, this will probably be their biggest home game that isn't Stanford (just due to rivalry) in a while tbh. They'll be off to their first 4-0 start since 2019. That year they started 4-0 with wins against Washington and Ole Miss on the road, got ranked 15th, and played ASU at home week 5 and lost. But ASU was unranked. Also the last time they had a top 10 team play them in Berkeley without already having like 4 losses was 2017 against #5 USC when they were 3-0 with wins against Ole Miss and UNC.
If Cal ends up ranked after this week (possible) it'll be the first time they hosted a ranked opponent while they were ranked since like 2009. So I wouldn't be surprised if this is like the best non-stanford turnout they've had in like a decade..... if they are ranked at least.
