How is it not necessary or smart?
As we all know, BC's version of the WCO is very complex and hard to understand, and every extra minute Freeman gets will do nothing but benefit the youngster.
He will come in, get reps with the offense during the spring game next year, and be playing against college competition for more than 8-9 months before his eligibility as a college-athlete begins.
Every rep and every moment this guy stays on the field and is learning is nothing but of value. Him enrolling early is a GREAT thing, since he will be a QB especially.
