WALTHAM — It was a day for coronation.
Two would-be cornerstones of Boston’s basketball future – Marcus Smart and James Young – were formally indoctrinated publicly into the Celtics  mystique on a six-seat dais on the team’s practice facility court. In five days they head out for the NBA Summer League in Orlando on their first basketball excursion as formal members of the most hallowed team in the NBA.
Celtics president of basketball operations Danny Ainge, co-owner Steve Pagliuca, head coach Brad Stevens  and team president Rich Gotham introduced first-round picks Smart and Young on Monday at the club’s training facility on Monday, three days after they were chosen sixth and 17th overall, respectively, last Thursday in the NBA draft.
“We’re just excited to be here,” Smart said. “We embrace these banners. It means a lot to us, the tradition that’s here. We just want to go out and play our game and just feel part of this tradition and embrace it all.”
“Really just come out here and do what we did to get to this point,” added Young. “The empty banner up there, just look at it as motivation, that’s about it.”
As was the case before the team won the 2008 NBA title, there is a blank white banner with green trim next to the team’s last NBA title banner up on the wall in the practice facility.
Family members of both draft picks were on hand and formally welcomed by Ainge during the 15-minute press conference at the Sports Authority complex in Waltham.
