Honestly? In terms of baseball attendance, they traditionally outdraw Kentucky, Georgia, Mizzou, Tennessee, Vandy. Similar to Auburn, Bama, Florida. Clearly behind State, OM, LSU, USCe, Arky, and aTm. Probably clearly behind Bama now in the new stadium and will be caught by Kentucky in their new palace.
Outside of the SEC, they are clearly behind Clemson, FSU, TCU, and Texas. Similar to Texas Tech and Miami.
They are always among the top 2-3 outside of the SEC/ACC/Big12 along with Louisiana Lafayette and East Carolina. They generally hover between about #15 and #20 nationally in attendance. And I might be wrong since it's been a few years since I was out there, but I don't think they count the people in right field behind the fence either.
They aren't on the MSU/OM/USCe/LSU/aTm/Arky/Texas/TCU baseball support level. But they are on the next tier behind us IMO.
