6. Linval Joseph
At 24, Linval Joseph is already on the fast track to anchoring the middle of the Giants defensive line after an impressive 2012 season. With 108 tackles and six sacks over his first two full seasons as a pro, it felt like Joseph's name was called a lot, especially in 2012.
With the majority of this list of 25-and-under players coming from the defensive side of the football, it's apparent that the Giants are going for youth on their defense and trying to build a solid core of young players. With continued improvement, Joseph can become a major factor for the defense in the coming years.
