If Sione Vaki is focusing on offense, who’s taking over at safety for Utah?

Presuming the breakout wildcat/running back reduces his workload in the defensive backfield in order to maximize his energy, the two most likely candidates to replace him are former starter Nate Ritchie and true freshman Johnathan Hall.

(Mark J. Terrill | The Associated Press) Utah safety Nate Ritchie, right, going for a tackle against USC running back MarShawn Lloyd, is a candidate to move into the starting lineup, or at least get a significant bump in his snap count, if Sione Vaki becomes a primarily offensive player going forward.
