The Cyclones picked up their third commitment on Friday when Nate decided to join his brother Nick at Iowa State.
At 6-foot-2, 270 pounds, Nate will play nose guard for the Cyclones. Nick, a linebacker, was a freshman on last year's ISU squad.
Nate drove up from Muscatine for Friday's padded camp and committed afterwards.
He said the football program sold itself to him; his brother was a minor factor.
"Sure it's good that he's playing already, but he really didn't come into the picture when it came to me picking where I wanted to go to college," Nate said.
"[I got] to know the coaches better at camp and worked with them one-on-one," he said.
Over the next couple of months Nate said he'll focus on a couple of areas to improve in – mainly his foot speed and strength.
