Madison — Iowa's players have waded into unfamiliar territory:
Unbeaten through four games.
"It was another very positive step forward for our team to finish September 4-0," Iowa coach Kirk Ferentz said after the Hawkeyes' 62-16 victory over North Texas. "We're really pleased about that. I think the guys have worked hard, certainly week-in and week-out. They showed up today ready to play.
"And, again, we are really pleased about finishing this game or this month in a strong fashion."
Iowa (4-0), which opens Big Ten Conference play at Wisconsin (3-1) at 11 a.
