Marble, who moved from point guard to shooting guard this week, converted the three-point play for his 17th point in only 6 1/2 minutes.
“The reason we moved him back to the two-spot is to get him all over the floor with the ball,” McCaffery said. “That’s where he’s at his best.”
Marble came within four points of tying his career high despite playing only 20 minutes. He finished 9 of 13 from the floor and sank all six of his free throws.
“I’m just being more aggressive, looking for my shot more and being more assertive,” Marble said. “At the same time, I’m still trying to make the right plays. I’m still a playmaker with the ball and finding open guys.”
The Hawkeyes shot 62 percent from the floor to eclipse the 100-point mark for the second-straight game. Iowa made nine of 21 3-pointers.
Abilene Christian — new to Division I this year after playing 31 years in Division II — is off to its worst start since 1990. Abilene Christian committed 19 turnovers and had only six assists on 14 field goals. The Wildcats shot just 26 percent for the entire game.
“It’s a hard one because I didn’t really think about that until we were up over 30 at the 16 minute mark, so we had 16 minutes to go and I’m going to get some of my guys out, I’m going to put the next group in,” McCaffery said. “It’s kind of like let’s just keep playing hard man-to-man defense, keep running the fast break, keep moving the ball. Don’t stop playing that way. We’re not going to sit here and dribble out 16 minutes.”
Iowa, now rated in one poll and just outside the ranking in the Associated Press, is off until hosting Ivy League challenger Pennsylvania Friday night at 6 p.m.
