Someone asked Campbell about this in his presser. Talking about criticism for offering so many guys.
Campbell said something along the lines of, if anyone, coaches, parents, or players says that we are being dishonest with their kids or trying to mislead them, then there's a problem. They aren't trying to bamboozle kids with offers. They aren't pulling scholarships on signing day to get a higher rated recruit. They will fulfill these offers.
It's not like the SEC used to do all the time where they'd sign 30 guys on signing day and send the worst 5 packing or expect them to greyshirt.
