Friday’s roundup: Celtics welcome big man Al Horford

Associated Press

Waltham, Mass. — Al Horford is the biggest free agent ever to sign with the Celtics.

And he’s going to try to make sure he’s not the last.

“People around the league, they appreciate, they understand how special it is,” Horford said Friday at a news conference surrounded by championship banners at the Celtics’ practice facility. “I hope that if I’m coming here, it will definitely open the door to other free agents.”

Horford agreed to a four-year, $113 million deal with the Celtics last week on the opening day of NBA free agency. A few hours later, he learned that Kevin Durant had spurned Boston’s offer and decided to sign with the Warriors instead.

“It would have been nice, but I have to move on,” Horford told reporters, after he was introduced but before the contract had been approved by the NBA office.

Without Durant, the Celtics missed out on a player that could have elevated the team into immediate contention for the franchise’s 18th NBA title. General manager Danny Ainge conceded that Horford alone doesn’t do that, even on a roster that already included All-Star Isaiah Thomas.

“Right now it definitely makes us better,” Ainge said. “We’re not done. We still have work to do.”

The news conference was delayed at the start because of a paperwork problem that kept the Celtics from saying Horford was officially signed. Owner Wyc Grousbeck said it was just a formality, but in the meantime they were only “welcoming” Horford to Boston.

That didn’t stop the player’s wife from taking a panoramic photo of the 17 NBA championship banners ringing the practice court. The numbers on the scoreboards had all been changed to “18” — the next Celtics title.

“He might not have seen it, there’s a blank banner up there on the right,” Grousbeck said. “We’re hoping to work together on that.”

The Celtics have all those banners and retired numbers, but NBA free agents have traditionally been drawn more to the attractions of South Beach or the media possibilities in New York and Los Angeles. Boston has signed some big-name free agents in the past — Shaquille O’Neal and Dominique Wilkins among them — but only at the end of their careers.

During Ainge’s last roster rebuild, Timberwolves big man Kevin Garnett balked at coming to Boston — in a trade — until Ray Allen was acquired — also in a trade — and added to a roster that already had Paul Pierce. Now that the Celtics have Horford, they could be a more attractive destination for the next crop of free agents.

“It’s a great organization. There’s a lot of history here,” Horford said. “I feel like everyone around the league respects it. That’s a big part of the reason why I chose to come here.”
