IOWA CITY — It was a quick hook.

Ahmad Wagner had a turnover in front of the Iowa bench 25 seconds into Friday’s game, and Iowa basketball coach Fran McCaffery immediately motioned to freshman Jack Nunge to go into the game.

When Nunge entered the game at the 18:37 mark, McCaffery immediately grabbed Wagner for some quick instruction, then sent him back to the scorers’ table to check back into the game.

McCaffery had said before the season he wasn’t going to be afraid to use anybody and everybody, and the sub-in-sub-out 83 seconds into the season showed that he’s not kidding.

The Hawkeyes’ 95-62 win over Chicago State in the season opener at Carver-Hawkeye Arena figured to be one of those nights when every player expected to be in Iowa’s rotation was going to play plenty of minutes.

It was a full box score. Ten players played 13 or more minutes. Six Hawkeyes scored in double figures.

Wagner expects that all the time.

“Practices are like a war zone,” the junior forward said.

Nicholas Baer and Connor McCaffery were the only rotation players who didn’t get into the game. Baer is out three weeks with a fractured finger, and McCaffery was an unexpected scratch because of a sprained ankle.

It was an impressive offensive show for the Hawkeyes. Luka Garza went 6-of-6 from the field, Tyler Cook went 4-of-4 — he’s made his last 22 shots dating back to last season — and Isaiah Moss was 5-of-7.

The Hawkeyes went 31-of-52 from the field, 12-of-22 in 3-pointers.

That’s something Fran McCaffery expected, especially from behind the arc.

“I’ve never had a team with this many 3-point shooters, and two of them didn’t even play tonight,” he said.

McCaffery went with all sorts of lineup combinations, including one that had Nunge and Garza, both at 6-foot-11, playing together.

Nunge added 10 points, and combined the two freshmen had nine rebounds.

“They have great confidence, demeanor,” McCaffery said. “They don’t rattle. Really impressive, those two guys.”

Garza had 16 points. Moss had 14. Cook had 12. Jordan Bohannon had 12 points to go with six assists — he didn’t have a turnover. Nunge and Maishe Dailey each had 10.

NOTES: Iowa had a 38-33 rebounding edge. … The Hawkeyes had 23 assists against 17 turnovers. … Garza had three blocked shots.
