Top RB classes reside in SEC

We've assigned class grades and done our class rankings. Now it's time to see which schools brought in the best class at each position. When looking at the running backs, the SEC once again loaded up with some of the top classes.

Top RB Class: Alabama Crimson Tide

Counting five-star athlete Derrick Henry, who is heading to Tuscaloosa to play running back, the Tide have four ESPN 150 backs all ranked among the top 10 RBs. Henry has some question marks with his jumbo size and somewhat upright running style, but in this downhill offense, he could fit in and develop into the ultimate load back. Alvin Kamara, the No. 4 RB in the country, is more compact and balanced and perhaps more of a big-play college back than Henry or the powerful Tyren Jones, the nation's No. 8 RB. Keep an eye on Altee Tenpenny, the No. 10 RB who, when healthy, might be one of the most explosive of this deep stable of Alabama backs in the 2013 class.
