The 6-foot-2, 250-pound defensive lineman told CSR that Iowa State has been recruiting him since this past spring.
"Coach (Shane) Burnham came down for my spring scrimmage and then not long after that I got my offer from them," said Rayner. "We stay in touch and we've been mainly just talking about the school and Iowa State also sends me a lot of letters."
Adarius runs a 4.8 40-yard dash which might be the reason that the Iowa State staff has wavered on which position they would want Rayner to play if he chose Iowa State.
"At first they wanted me at defensive tackle but then later Coach Burnham told me that they would want me at defensive end," he said. "He told me that they really like how I get up the field and how I rush the passer. They also like that I make a lot of tackles."
Adarius currently holds six scholarship offers but told CSR that he has already cut that list down to three.
"If other schools offer me they could join the list but right now my top three are Indiana, Iowa State, and Colorado State," he said. "I plan on taking visits to those three and maybe a few others and then I'll make my decision later this fall or after the season."
