So the two sophomores don't even know each other.
But Kellogg certainly can relate to Heytvelt, suspended indefinitely by Gonzaga after beingarrested two weeks ago and charged with felony possession of a controlled substance.
"When I saw that on TV, I just shoot my head," Kellogg said. "It wasn't really a laughing matter. What he's got to deal with, with his family and friends and everybody seeing it on a national level, it's difficult."
Kellogg understands because he has been down a similar road. Booted off the team at Connecticut two years ago, Kellogg received two years probation after arrests for possession of marijuana and attempting to assault a police officer at a campus dorm.
The former McClymonds High standout got a second chance at USF, and is grateful. He enters today's West Coast Conference game against the second-place Zags as his team's top scorer (15.1 ppg) and the league leader in steals (2.36). He's also second among USF players in rebounding (4.6) and assists (3.4).
"The University of San Francisco has been real good to me, helping me out in every way they can," Kellogg said.
Heytvelt, a 6-foot-11 sophomore who ranked third in the WCC in both scoring (15.5) andrebounding (7.7), may or may not play again for Gonzaga.
"Everybody makes mistakes, nobody's perfect," Kellogg said. "He's got to listen to the right people, try to block all the negativity out. The most important thing is how he's going to bounce back."
Kellogg said his abrupt departure from Connecticut, a high-profile program in the Big East Conference, was a slap in the face.
"It got me realizing what's really at stake ... how one bad decision can tarnish everything," Kellogg said. "I hope (Heytvelt) will be all right."
For Kellogg, this has been a season of trying to settle in as a player, a student and a member of the USF community. Coach Jessie Evans said Kellogg is making progress.
"He's grown tremendously, not only as a player but as a person," Evans said. "He's more pleasant to be around now. He's more endearing now. He was less endearing when he was younger."
Kellogg said he is trying to make better decisions. "I'm thinking carefully, thinking twice," he said. "I'm just being careful in what I'm doing, where I'm doing it and how I'm doing it."
It may take a "village" to raise a point guard at USF. Evans said athletic department tutors and even professors are taking a "hands-on" interest in Kellogg's progress.
In late January, the administration had Kellogg sit out three games, including the road trip to Gonzaga, to focus on his schoolwork. "It was the right thing for me," he said. "I don't think I should have any more problems."
Likewise, Kellogg is trying to develop consistency in his game. He's had separate games of 37 points, 10 rebounds, eight assists and seven steals. He also has the high total of 106 turnovers, and needs to work on making his teammates better, according to his coach.
"He does it at times, but he's not consistent," Evans said. "He has so much energy ... and he wants to be the person who hits the home run every time. Sometimes that's not needed."
"I would say I've yet to put together two (consecutive) solid games," Kellogg said. "Consistency has been a big part of it. I guess I'm expecting too much out of myself."
In Kellogg's case, that's probably a good thing.
