They're still names. They won't always be down. B1G will be the #3 or 4 league in the land next year after being #5 or #6 for the past decade (and #15-20 before Nebraska joined)
The big 10 will go up a spot in the rpj just simply because the pac 12 will cease to exist.
Big 12, acc, and sec will still be the top 3 conferences for baseball.
Since 2020 the big 10’s rpi ranking
2020- 10th
2021 - 11th
2022 - 8th
2023 - 6th
2024 - 4th
2024 is the conferences best year by far but the gap between 3rd and 4th is huge. The gap between 4th and 8th is smaller and I’d bet on the big 10 dropping a couple spots because they typically fall during conference season.
USC and UCLA don’t really elevate big 10 baseball more than Nebraska did which has been marginal at best.
USC hasn’t been a baseball school since the late 90s and puts no money into it.
UCLA has been better this century than any big 10 team. They also suffer a fate of zero financial support. And once John Savage retires it could just collapse on itself.
