I don't think Cade will sign anywhere on the 20th. He will wait until NSD.
The kids who will sign on the 20th are the ones who are gung-ho for a certain school. The one's who want to leave their options open won't sign anywhere early.. Especially the 5 stars. They like to make a big spectacle on NSD.
Cade is an early enrollee so yes he will sign during early period
