DES MOINES - Stars possess gravity that causes everything around them to collapse in on them.
Seven-foot-1 Sioux City East center Adam Woodbury has experienced this phenomenon countless times.
It just so happens he's orbited by a collection of smaller stars.
The Black Raiders got contributions from all around the horn and locked up the West Des Moines Valley offense to claim a Class 4A quarterfinals win Wednesday at the Iowa High School Boys State Basketball Tournament.
The Univeristy of Iowa recruit Woodbury finished with a double-double of 12 points and 12 rebounds, but he was the low-scorer of a quartet of East players in double figures.
JC Fuller scored a game-high 19, Alex Imming 16 and Marcel Dunson 13 as Sioux City East (20-3) advanced to Friday's semifinal contest against Ankeny at 1:30 p.m. inside Wells Fargo Arena.

"They put three guys on me, they didn't think a couple guys could step up and make shots," Woodbury said, "but we ended up proving them wrong and got the victory.
"We had some guys step up in major roles."
Fuller entered the game actually leading the Raiders in scoring while Imming adds an average of 12.1 per night, but Dunson doubled his per-game scoring average this day.
"They left (Dunson) open and I told him at halftime, 'Make them pay. If they're going to keep leaving you open, make them pay,'" Fuller said. "And he did. He stepped up in a big way."
East looked like it would leave the Tigers (18-6) behind in the third quarter when it took a 48-32 lead with under 2 minutes remaining, but Valley finished on a 7-0 run and added another two to start the fourth to draw within four, 48-44.
A 10-2 run by the Tigers put them up 54-52 midway through the fourth quarter to complete the comeback - momentarily.
"We talked about it before the game. If we're up 10, 12 with a minute to go, it's not over. They can shoot the three," said East head coach Ras Vanderloo.
The Black Raiders, however, responded with a 12-1 run to regain control, though they were unable to completely slam the door until the final seconds thanks to 12-of-22 shooting from the foul line in the fourth quarter.
Valley shot 34 percent from the field for the game and traversed a nearly 12-minute long drought without a field goal over the second and third quarters.
Partial credit goes to Woodbury, who finished with three blocks and altered plenty more.
"He's so big in there, you're not really getting a lot of second shots and our kids were kind of afraid to go to the basket and just finish on him," said Valley head coach Jeff Horner.
"We've just been struggling shooting the ball the last three games," he added. "It continued."
Valley senior and Northwestern recruit Kale Abrahamson scored 13 points while teammate Nate Meyer added 18. Highly recruited junior Peter Jok had 10 points and eight boards.
East shot 51.3 percent from the floor as defensively the Tigers went with a triangle-and-two that attempted to "pretty much surround Woodbury with hopes that Dunson and Godfrey would have to make a couple shots," Horner said, "and give Dunson credit. He came out, hit a couple shots."
