Seth Curry discusses the message he got from his brother, Steph, and what it'll be like competing in the Western Conference finals. (0:41)

DENVER -- Dell Curry and Sonya Curry emerged from a restaurant inside the Pepsi Center and shouted with joy as they hugged Seth Curry.

The Curry family celebrated the Portland Trail Blazers' 100-96 victory over the Denver Nuggets in Game 7, setting up a Western Conference finals that will be a Curry family affair.

Seth Curry will face Stephen Curry for the right to get to the NBA Finals when the Trail Blazers play the Golden State Warriors starting Tuesday in Oakland, California. It's the first time in NBA history that two brothers will play against each other in a conference finals or NBA Finals, according to Elias Sports Bureau research.

"It's a dream come true for both of us," Seth Curry said. "Obviously, it's the first time it's been done. It's going to be a lot of fun for our families to be in the building. I'm looking forward to it."

Seth says he has played against his brother only in the NBA. Steph is 7-2 in the nine meetings, but his two losses have come this season.

"It's going to be so much fun," Sonya Curry told ESPN. "It is. From our end, to see both of our sons to compete at this level and for the goal to be a championship is such a blessing. We never could imagine this.

"One of them might go home. But we're going to the championship!"

No matter what happens, the Curry family wins. Either Steph will be going for his third straight championship or Seth will be playing for his first title. Seth says the experience could be stressful for their mom, however.

"I know my mom is a little stressed out," he said of what usually happens when the brothers face each other. "My dad, he's always calm. But my mom is stressed out, and you might be able to hear her. She's probably happy right now, enjoying the moment for both of us. She can look at the bright side: One of us is going to the Finals at the end of the day, so there's no losers."

Dell and Sonya Curry have been traveling all over to keep up with their two sons this postseason. This is Seth's first time playing in the playoffs in his five seasons, and his parents have traveled to Oakland, Portland, Los Angeles, Houston and Denver. Dell Curry says the only games they missed were road games at Oklahoma City and Game 1 between the Blazers and Nuggets in Denver.

"It's going to be fun," he told ESPN. "It's going to lessen our travel schedule. That's the biggest thing. We've been traveling quite a bit. It's been fun, it's been tiresome, but it's about ready to get real now.

"It's a first experience for all of us," he added. "Biggest thing is we are trying to decide who represents who."

Sonya Curry has a solution for which parent will wear Blazers colors and which will wear Warriors gear.

"We are flipping a coin every game," she said.

She also said she will try not to stress out watching both of her sons play with a Western Conference championship on the line. She wants to see both of her sons have their moments, especially Seth in his first postseason.

"It's fun," she said, repeatedly calling this a blessing. "It is, really. I actually look forward to watching Seth and doing that. I want him to steal the ball and want him to shoot over Stephen and all that good stuff. I want him to have his moments too.

"It's cool. It's such a blessing to just be able to watch this and experience all this."
