"The experience was great, there were competitors everywhere, and the players were faster, stronger, taller and bigger," said Calhoun. "I loved it because it was hard work. Everyone is from around the country and they were all really fast. I thought the drills went good. I just have to work on my feet more, doing a better job of jamming and not lunging and I could work on my speed some."
Calhoun worked with the linebackers at the combine, but some schools like him as a safety.
"I want to play safety too, but I love linebacker because I love hitting," said Calhoun.
The 2014 prospect already has a handful of offers and a couple more could be coming soon.
"Washington, Nebraska, Arizona State, UCLA and Utah have all offered me and I would say that Washington State, USC and a couple of others could be close," said Calhoun, who's sister plays basketball at USC.
Two schools, though, stand out for Calhoun.
"UCLA and Arizona State are my top two schools right now," said Calhoun. "I'll take some visits in the spring and summer and then probably some official visits as more offers come in."
Calhoun was at the UCLA-Arizona game, when he was offered by the Bruin coaches, and defensive line coach Angus McClure stopped by the school earlier this week.
He's planning on taking in a few more camps and combines in the spring and summer.
"I played in the USA vs. the World game this summer, so I might go to that camp in Austin in February and then I'll be doing the Nike Camps and some college camps this summer," said Calhoun.
Calhoun said he's hoping to get up to 205 by the spring.
