The Irish's leading rushers from a season ago—Cierre Wood and Theo Riddick—have taken their talents to the professional ranks, leaving their vacant position in a state of flux.
George Atkinson, a former 4-star prospect in the 2011 class, is the most experienced of the bunch left behind, which also includes Cam McDaniel, William Mahone and Amir Carlisle (Carlisle will not participate in the spring game while recovering from a broken collarbone).
How Kelly divides the blue and gold teams will go a long way in determining who will receive the most carries, though it's fair to assume that Atkinson and Mahone will earn the most looks.
McDaniel has flown under the radar at Notre Dame, which has included a switch to cornerback last fall, but he remains a fan favorite. In this humble writer's opinion, McDaniel is this team's "Rudy."
Now that three-year starter Braxston Cave is pursuing his dreams in the NFL, his vacant center position has come down to a two-man race between Matt Hegarty and Nick Martin.
Since committing to Notre Dame nearly three years ago, Hegarty has been presumed as Cave's heir apparent, though Martin has since challenged that notion.
It's a position that likely won't be solved after the spring game and will carry into the summer and fall camp.
