It's a new position for Calhoun, but one that might make sense given that junior SAM Salamo Fiso and senior WILL Antonio Longino have played well in camp and seemed to solidify their spots atop the depth chart.
Calhoun's strong play in camp coupled with ASU's challenge at Devil backer created the opportunity for this to be explored.
Elsewhere on the defense, sophomore Armand Perry took first-team reps at the field safety position for the first time Monday even though sophomore James Johnson returned to practice after hurting his shoulder a day earlier.
With ASU concerned about coverage and speed on the back end in the wake of the loss of Damarious Randall to the NFL, Perry might be the best option.
