I’m on the phone with Jayson and Jaylen,” said former Celtics assistant Jerome Allen. “I’m saying, ‘Come on, man. Y’all got to figure this out.’”
Allen wasn’t nearly alone.
“Everybody was saying the same thing: We’ve gotta figure it out,” said Brown. “But nobody was trying to help us figure it out. And that’s how Joe was different. He showed us how. He helped break down the game and see where you could be better, see where you could make the game simpler and easier. He really laid it out for us in some of those film sessions. And that’s what the difference was.”
One difference now? The Celtics have turned the lessons of last season into an even more fluid offensive system.
“We’ve been playing freely,” Smart said late in the regular season. “We don’t have any chains on. That’s not saying that last year we did, it’s just even more evident this year to let us just play. And that’s the thing that Joe has been preaching. He wants us to play. He just wants to be here when we need him. And we love Joe for that.”
The Celtics roster has undergone significant changes since the beginning of last season. From top to bottom, Brad Stevens filled the supporting cast with high-IQ players. White and Brogdon gave the team more maturity and playmaking. Mazzulla asked Smart to organize himself and his teammates into the right places at the right times.
The Celtics still needed Tatum and Brown to progress in understanding the game. Near the beginning of the season, Mazzulla posed a simple question to them: What would an opponent walk through at shootaround on the day of a game against the Celtics?
“And they didn’t have an answer,” Mazzulla said.
From there, the Celtics continued enhancing their awareness of what teams would want to take away from them. Once they understood what teams would prepare to stop against them, they needed to figure out their own counters to the strategies. Mazzulla wanted his players to see the game through the lens of “if-then” scenarios. If an opponent used one coverage, then the Celtics would handle it a certain way. If an opponent pivoted to a different plan, then the Celtics would adjust themselves. Mazzulla said he sees the game as a string of problems on both ends of the court.
“And you have to be ready to just solve problems,” said Mazzulla. “And those two guys are very open-minded to problem-solving. Once the game became if-then — if this, then that — I think that’s where they really grew.”
Mazzulla said he sometimes installed actions the day before a game. When he did, he said Tatum and Brown “executed the reads the next day in the game to a T.”
“(The offense) changed because now we’re able to open it up to where we have plays, we have specifics, but it’s those guys really,” said Mazzulla. “It’s more about, like, OK, here’s the concept. How can you two use your talent, your skill and your mind to get to what we want to get to? From then until now, it’s been really the genesis of our offense because of those two guys’ buy-in and their time spent doing that.”
Smart believes the Celtics were headed toward this style this season, with or without Udoka, who was suspended days before training camp and eventually replaced on a permanent basis by Mazzulla. Indeed, both Udoka and Stevens preached the importance of additional player movement after the team’s Finals loss to the
Golden State Warriors. During that series, Smart said the Celtics players noticed the difficulty of guarding an offense built on motion and flow rather than sets.
“It was tough to guard,” said Smart. “We know we had just as much talent as those guys if not even more.”
Maybe so, but Boston’s offense stalled out in key moments throughout that series. The Celtics led by five points with 7:32 remaining in a Game 4 loss but scored just six points the rest of the way. Afterward, Tatum blamed the drought on stagnation. His recognition of the problem failed to stop it later in the series. Boston trailed by just one point entering the fourth quarter of Game 5 before scoring just five points over the first eight minutes of the period.
“A lot of times when we played against teams, they knew what we were running and they knew what we were doing,” said Brown. “And we would still be able to be effective, but our offense wasn’t as good as it should have been throughout the playoffs. Our defense was fantastic but our offense wasn’t as good as it should have been.”
At the end of the six-game Finals loss, Udoka said the Celtics needed to improve their collective team IQ. They eventually did so within an offensive system designed to let the players think their way out of issues.
“For us it was just, it’s tough to guard all five of us,” said Smart. “If you’re moving around and you just create randomness, that’s kind of tough because now they don’t know what’s going on. Because they’re (thinking), ‘(
The Celtics players) don’t even know what’s going on. They’re just running stuff.’ It’s like, ‘How can we guard that?
They don’t even know what they’re running so how do we know?’ And it just makes it a little harder to scout when you can just go out there and say we’re just going to pass the ball, screen and cut and not run any plays.”
Opponents adjusted. Midway through the season, Brown said he could sense teams had scouted some of the Celtics’ randomness. They knew what Boston’s reads would be. He noticed defenders starting to top lock the Celtics’ wings — covering them on the opposite side of the basket to take away a path to the perimeter. That forced Boston to come up with new answers.
For Brown and Tatum, that has become a constant quest. Smart believes their mindset has shifted with experience.
“Just the way that they’re able to adapt to the game,” Smart said. “It’s tough when you’ve got a specific agenda that you’re supposed to do. If you’re a scorer, you’re supposed to score the ball. But what happens when every other team knows you’re trying to score the ball? Can you adapt? Can you still do things to win the game even if you’re not scoring? And that has shown.”
Mazzulla said Brown and Tatum used to know exactly where their shots would come from and how they would produce those looks.
“But I think a part of the development of really good players is that defenses are gonna take all of that away,” said Mazzulla. “That’s actually a compliment. That’s how good you’ve gotten is they’re going to take that away. Now what? So you have to be able to manipulate the environment, you have to be able to then create one on your own.”
That reality led to the latest step in Boston’s evolution.
“Now, if you don’t have a play,” said Mazzulla, “how are they going to guard you?”
