When New Orleans Hornets guard Austin Rivers visited the Boston Celtics on Wednesday night to face his father Doc Rivers' team, it was just the fourth time in NBA history that a father has coached against his son.
Maybe even more rare on Wednesday, Eisenhower High School girls basketball coach Mike Logue coached against his own daughter.
Allegheny-Clarion Valley (Foxburg, Pa.) happens to be the team of sophomore starting point guard Erin Logue.
When all was said and done, AC Valley defeated the Knights, 55-37, and Erin got bragging rights in the household, if dad allows her to use them.
Dad, or Coach Logue, drives to Eisenhower High School every school day to teach (it's almost two hours between towns), and coach the Knights. It often takes care of itself, as Erin and AC Valley play their games on different days than the Knights.
"Tuesdays and Fridays after practice I usually bolt out and head out to the game and watch her play," said Mike. "I get to see her a lot because (we play games on different days)."
Before the season the programs tried to work out a tournament to play in so Coach Logue could see his daughter play, and at the same time coach his Lady Knights. The only possibility the teams would meet would be in the tournament's championship game. He wouldn't worry about it unless it came to that.
But when tournaments fell through, each team had two vacant games on their scheduled, and this was a perfect fit.
Unless you're in the Logue household; then it might seem kind of awkward.
"It was very different," Erin said after the game. "I was kind of expecting him to say something to me (during the game)."
Like he does when he's Dad.
"We each had a job to do," said Mike.
But Erin couldn't help but glance over at her father on the sideline a few times during the game - when she did something well, and when she didn't, she said.
"She handled herself really well," said Mike. "We put our best defender on her."
Coach Logue said he was proud of how both Erin and his players handled the experience. Erin knows a lot of the Knights, and plays in summer 3-on-3 tournaments with some of them.
"She pretty much knew what I was going to do, and what we were trying to do as a team," said Mike.
"They also knew what I was going to do," said Erin.
Logue admitted there were a couple moments - then he said, "one in each half," in which there were a couple of "that's my daughter" moments. "I knew it was coming" kind of moments, he said.
Erin was on the right side of the court, dribbling with her left hand down the court, drove to the hoop and made a left-handed finger roll.
An Eisenhower assistant coach asked Coach Logue, "Who taught her that?"
In all, both coach and opposing player, father and daughter, wanted to win the game for their own team.
"It was very competitive," said Mike. "The trash-talking in the house started about a week or so ago. It was good-natured. I kind of enjoyed it."
With her father in the background, Erin said, "Oh, yeah, there's a lot of satisfaction (to beat him)."
Just like a daughter would say.
How about father?
"He's laughing," said Erin.
And also circling Feb. 9 on his calendar - that's when AC Valley visits Eisenhower.
