Calhoun is a 6'0", 215-pound defender who currently plays linebacker. He may appear to be undersized, but this is a thickly built athlete on the hoof.
A tough player, Calhoun is a good athlete who has excellent speed and quickness. He quickly finds the football after the snap, charges to fill alleys and has the short-area quickness to beat bigger offensive linemen to spots laterally to make plays.
When Calhoun does encounter blockers, he plays bigger than his listed size at the point of attack. He does not shy away from lead-blockers, resists being dug out of lanes and is stout upon contact.
The California native is at his best when he can attack the line of scrimmage, as he displays explosive movements in the box and when challenging offensive players. Calhoun's speed, athleticism and ability to buzz into coverage allow him to be a threat against passing plays.
He flashes the skills to latch on to running backs and tight ends as a man-to-man defender, can flip his hips to re-attach himself to his man at junction points and could play safety at USC.
