The big time southern programs, in most cases, have 6-figure operating budgets, for football alone, and the coaching positions are full-time. They are not school faculty members looking to make some extra coin. I remember attending a Nike Coach of the Year Clinic and listening to Rush Propst, former HC at Hoover HS in Alabama. He became nationally known on MTV's "Two-a-Days". He made upwards of 100K (for football alone) and the football team's operating budget was close to a million dollars. The majority of the monies were raised through boosters. Subsequently, Propst's Hoover career ended in scandal and he was removed. He has since moved on to Colquitt County HS (GA) where his base salary is $95,000. I understand the point you were trying to make, but your comparing apples and oranges. In contrast, Tom Brockett, I believe, makes less then $4,000 per year as Ansonia's head football coach.
History has also shown that CT kids from small schools have gone on to make an impact at the next level. Dwight Freeney did pretty well for himself coming out of Bloomfield. I think Newsome will go through some growing pains adjusting to college life and the playbook, not the physical aspects of the game. He started the camp and combine circuit as a 7th grader, so he won't be surprised by the talent or the speed of the game. He also will be as physically prepared to play as anyone on the roster.
