Grades have to be pretty positive thus far for the two coordinators. Olson essentially went into the season with a partially shattered offensive line and has found ways to move the ball. Tarver has obviously been lights out, putting together a scheme showcasing and utilizing the versatility and speed of the Oakland defense.
Chip Kelly better come prepared with something special or it could be a very, very long day for Foles.
