As for the student, Sam posted that he is stubborn and exhibits poor posture. As for the student's playing abilities, I don't remember Sam ever saying anything about this. Pointing the horn down is not the norm but you are right and I stand corrected, The student should not be messed with. Sam said "like an over-bite". If the student truly has a over-bite then he should be seen by a dentist or mandibular expert as an over-bite can come with it's own special problems both orally and psychologically.
