Just from casual observations he appears to be solid at the point of attack and capable of getting to the second level on zone plays. On Staffords QB sneak yesterday, Shelton executed a perfect double team with Allen. Watch Shelton get hip to hip and shoulder to shoulder with his center on that play. The result was a big push at the point of attack. The entire offensive line has really improved since the Rams inserted Sony into the backfield. So it is possible that Sony is somewhat responsible for their improvement. His style gels with their strengths and they feed off of each other.
