My understanding is they have the normal 25, plus 1 extra carry over from last year plus the 7, so 33.
The only way to get past that to 36 are grey shirts( promise of scholarship next year) or preferred walk ons.
I think the current NIL arrangements they have are only for scholarship players, so any payments to anyone beyond the 33 would need to be individual or new NIL arrangements.
It's likely only a matter of time before the big money programs figure out how to pay top players to be preferred walk ons.
