"They're worried about my size," the 2011 cornerback from Fort Myers (Fla.) South High said.
Crawford said he stands 5 feet, 10.5 inches and weighs 186 pounds. Those measurements work for Iowa, who extended him a scholarship offer on Tuesday. The Hawkeyes are the only BCS school to step up with a ride so far.
"I'm not sure what the other schools are waiting for. I'm already qualified (academically)," Crawford said. "But if Iowa is the only one to offer, I'm good with that."
Assistant Rick Kaczenski leads Iowa's recruiting of Crawford.
"It was very unexpected," Crawford said of the Hawkeye offer. "My coach said they showed a lot of interest, but I really hadn't had much contact with them. They said they'd been watching me the last three years and really liked what they saw."
Crawford threw for 2,629 yards and 25 TDs as a junior quarterback. He also produced 422 rushing yards and five scores. As a safety, he totaled 43 tackles and picked off 10 passes.
"I'll probably go in as an athlete, but I think Iowa is looking at me as a cornerback," Crawford said. "They said they like how physical I play. They like that out of their DBs."
Crawford said that he's watched Iowa on TV quite a bit.
Crawford said he wants to study medicine in college. He's also looking for honesty.
"I'm going to take my visits and check things out," Crawford said. "Distance isn't really factor. I'll play anywhere.
"I do want to connect with the coaches and feel like they're being sincere. I'm not looking for somebody to sell me a dream."
So far, he likes what he's hearing from the Hawkeyes.
"I'm definitely taking a visit to Iowa," Crawford said.
