The final update to ESPN 300 player rankings coupled with several significant commitments has led to some movement in the class rankings. Alabama continues to hold onto to the top spot as it heads for a fourth-straight No. 1 class on national signing day. The Crimson Tide landed their 20th ESPN 300 commitment with the addition of No. 2 RB Damien Harris. This well-rounded back with big-play ability and he could potentially come in and help replace some of the production lost with second-leading rusher T.J. Yeldon declaring for the NFL draft.

Tennessee slides into the No. 5 slot after not only adding ESPN 300 QB-DT Sheriron Jones, but also having a few committed prospects move up in the player rankings. What was already a very strong defensive line class, became even more impressive with big DT Kahlil McKenzie and DE Kyle Phillips getting significant bumps up, as well as pass-rushing end Marques Ford moving into the ESPN 300.

USC also got a bump up the class rankings following the updated player rankings. Recent Trojans RB commit Ronald Jones II is now the No. 1 RB in the nation and fellow offensive weapons TE Tyler Petite and WR Tristan Payton both moved into the top 100, helping to push USC to the cusp of the top five.

Outside the top 25, Nebraska was a big mover jumping up a handful of spots to No. 33. New head coach Mike Riley landed his highest-profile commit thus far, adding massive, mauling, top-five OG Jalin Barnett.
