Centennial's offense flows through senior forward Zach Tobey, relying on his post moves or on open shots when opponents double- or triple-team Tobey.
In Monday's Northwest Holiday Basketball Tournament second round game, Kellis rarely sent help to the post and the 6-4 Tobey had trouble scoring against 6-9 sophomore center Kenny Martin.
The result wasn't pretty. No Coyote scored more than seven points and Kellis (6-3) cruised to a 56-30 victory.
"(Martin) was definitely the difference tonight," Centennial coach Brian Hoffner said. "We were nine for 50 on shots in the post."
Centennial (2-7) stayed with Kellis for a quarter, trailing 12-10 at the end of one. In the second quarter, Kellis sophomore guard Demetrius Balark took over, scoring all nine of his points and pushing the Cougars' lead to 26-16.
The Coyotes scored the first three points of the second half, then were buried by an 11-4 Kellis run to close the third quarter. In this quarter, its was sophomore guard Wayman Payne's turn to lead the Kellis attack. Payne posted nine of his game-high 12 points in the third.
"The energy level was low and he concentration was lacking," Hoffner said.
Martin was the constant for the Cougars, blocking seven shots and altering countless others. On offense, he mainly stayed in the high post, hitting two 15-foot jumpers. Martin finished with eight points and six rebounds.
Forward Jarvis Lewis chipped in eight points and four rebounds for Kellis. Lewis also had some defensive duties on Tobey, who was limited to six points and six rebounds.
Junior guard Ed Mora led the Coyotes with seven points. The offense looked rudderless for most of the night, and Martin's length wasn't the only reason.
"Right now our point guard (Senior D.J. Harnden) is in California and that showed," Hoffner said. "He's not our best player, but he runs the offense well. We didn't get into good offensive sets all night."
Centennial plays in a consolation game at 4:30 p.m. Tuesday at Northwest Christian School, 16401 N. 43rd Ave., Phoenix.
