Good point, long arms are such a benefit. Ogden and Munoz had long arms besides being much bigger than their opponents and still having good quickness. If D'Brick can add 20-25 pounds of mass, increase his weightlifting by 20%, and still retain over 95% of his quickness....he'll be an All-Pro every year.
From what I recall, Gallery was the better prospect coming out of college. In fact, I remember most people saying that Gallery was as much of a "can't miss" prospect as there was.
