In the 100 days leading up to signing day 2015, RecruitingNation will be looking back at our ESPN recruiting rankings from 2006 to the present and count down the best player of the past 10 years at each ranking position, No. 100 to No. 1.

Matt Kalil, No. 73 in 2008 class

Kalil came out of uber talented Servite High in Anaheim, California, in 2008 as a lock for USC with his older brother, Ryan Kalil, having played for the Trojans and had a very successful college career. The youngest of two brothers, Kalil, chose the Trojans over Notre Dame, and was a member of a USC class that included Tyron Smith, Nick Perry, Jurrell Casey, Khaled Holmes, Malik Jackson and Wes Horton. Kalil's father, Frank Kalil, played college football at Arkansas and Arizona.

Kalil redshirted as a freshman in 2008 due in part to sprained knee. He spent his redshirt freshman season as a backup tackle with one start.

It was the 2010 season in which Kalil became a full-time starter, logging 13 starts at left tackle earning All-Pac 12 mention.

His fifth and final season in Los Angeles was a First-team All-American performance at left tackle. In addition to being selected to All-American teams, he also took home the 2011 Morris Trophy, which is awarded to the best lineman on the West Coast. He was the third straight USC player to win the award following Charles Brown in 2009 and Tyron Smith in 2010.

Kalil was selected fourth overall by the Minnesota Vikings in the 2012 NFL draft. He was selected to the Pro Bowl in 2012 and has started every game for the Vikings since being drafted.

Honorable mention: Devonte Fields, No. 73 in the 2012 class. Fields was on his way to All-American status before off the field issues led to suspensions. As a freshman, the Arlington Martin High product started all 13 games that ended with Big 12 Defensive Freshman of the Year honors by the coaches after recording 53 tackles, 18,5 tackles for loss and 10 sacks. Fields selected the hometown Horned Frogs over Texas A&M and Oklahoma.
