DES MOINES — There was never a doubt.

The Mississippi Valley Conference’s nightly battles made Wednesday’s quarterfinal game in the Class 4A state tournament a breeze as Cedar Falls cruised to a 75-47 blowout over Sioux City East.

Throughout a basketball season in which his team has endured five losses, including two to a pair of elite out-of-state teams, Cedar Falls coach Ryan Schultz would routinely meet with his staff and talk about the challenges at hand.

Those tests extended into a postseason in which the Tigers found more competitive substate games with Waterloo East and Dubuque Hempstead than they experienced in this state opener.

“Every night we’d get together as coaches and talk,” Schultz said. “Every last one of us would say just said how great our conference was from top to bottom this year. There’s not a night off, and that definitely helps us for these moments down here (at state). ... That’s made us a better team.”

Advancing to the semifinal round for the second time in three years, Cedar Falls’ margin of victory was the largest of any Class 4A opener, and second-largest among the 16 first round games at this year’s state tournament. The Tigers (19-5) will face No. 7 seed West Des Moines Valley, a 52-44 winner over North Scott, 8:15 p.m. Thursday for a trip to the final.

One of two holdovers from his school’s 2016 semifinal run, all-state standout AJ Green led Cedar Falls with 28 points, including makes on 5 of 11 3-point attempts, and seven rebounds. The Tigers’ other four starters combined to hit 17 of 24 shots as they quickly acclimated themselves to the Wells Fargo Arena stage.

Logan Wolf’s 17 points and six assists, in particular, were a valuable complement to Green’s effort.

“They’ve been playing great all year and everybody stepped up today, the juniors especially,” Green said. “Me and Ben (Gerdes) are the only ones who played in that state tournament two years ago. This being the first game for the other guys, they really stayed composed.”

Green also revealed composure. He followed an airball with three consecutive 3-pointers during a 13-3 run that gave the Tigers a 22-8 lead one minute into the second quarter. Cedar Falls later accelerated to the finish line with 44 second half points.

“If you miss, put it past your mind and think the next one is going in,” Green said. “My dad has preached that to me my whole life, and I was able to knock a few down.”

Cedar Falls was just as sharp on defense.

Jack Peterson’s 11 points paced a Sioux City East team (19-4) that made just 15 field goals. The Black Raiders’ leading scorers on the season, Van Rees and Aidan Vanderloo, were held well below their average with 9 points apiece.

Defensive adjustments had to be made for the Tigers after forwards Jack Campbell, Reese Gardner and Chase Courbat each picked up two early fouls. East finished 27 points below its season average.

“We knew when we switched to that 2-3 (zone) we had to really locate Van Rees, not let him work and do his thing in the paint, and then get to Vanderloo on the 3-point line,” Green said. “The guys down low on the zone really did a great job.”

Advancing convincingly, the Tigers showed they don’t get rattled easily.

“We’ve had some ups and downs as the season has went on, but I think we’re playing our best basketball right now,” Wolf said. “Moving forward we’ve just got to keep doing what we’re doing.”
