How good things were going for Doc Rivers  on Saturday?
His team was up 2-0 in the best-of-seven Eastern Conference finals against the Orlando Magic . His 24-year-old point guard Rajon Rondo  is playing his best basketball of the season. His team raced out to a 24-point lead in Game 3 and making the Orlando Magic look silly.
But what makes him most proud – as it would any father – is what his youngest son has accomplished.
Austin Rivers stands 6’3″, plays shooting guard for Winter Park High School and just led his team to its first state title in school history.
“That was awesome. That was one of the better experiences I’ve had as a parent, as a fan,” Rivers beamed when asked about his son before the game.
“Watching your kid win a state title when the school had never won in their history, it was an amazing feeling. I don’t know if you can get that feeling unless your kids do something like that. It was special.”
How good is his son?
“I can’t say how good he is because he’s my son,” Rivers said. “For me, I don’t know. I saw him at least 11 times. I got home a lot, games just worked out. They actually played a game here in Springfield, Mass., which was great for me because I got to see that, as well. I got home to see him a lot and that was great to do.”
Austin Rivers is considered a top 10 basketball prospect in the class of 2011.
Helping his son get into a basketball school would not, of course, be new territory for the Celtics  coach. His oldest son Jeremiah played basketball for Georgetown before transferring to Indiana University, while his daughter Callie plays volleyball for the University of Florida, where she dates Patriots draft pick and linebacker Brandon Spikes .
