Simply put, the margin for error when it comes to beating Celtics is very small for Sixers

The difference in a playoff series, in any sport, can be defined in a variety of ways as to why the winner was who it was. Sometimes the team that advances is just the better team. Other times it could be mainly due to an individual, and so on and so forth.

Friday night, the Boston Celtics took a 2-1 series lead over the Sixers with a 108-100 victory. Heavily favored coming into the best-of-seven series and owners of a 32-point win in Game 1, the dynamics have changed mightily since. A Sixers win up in Boston in the second game evened the series and then a see-saw game on Friday proved that this is a series that is much closer than most had anticipated. 

The difference? There is simply little, if any, room for error when it comes to the Sixers if they are going to pull out wins against the Celtics. Game-changing plays can be in the smallest of forms, like an offensive rebound allowed here, an inadvertent elbow for a technical foul there. A bad decision that leads to an offensive foul or a misstep on a drive to the basket that's called for a walk.

The Sixers played a terrific game on Friday. They played hard at the defensive end. They had to use an exorbitant amount of energy to get themselves good shots on the offensive side. They followed the blueprint that was formed by Nick Nurse and his coaching staff after pouring through hours and hours of tape. And it wasn't enough because of the small intangibles that you can talk about, but happen during the course of a game. Intangibles that the Celtics are brutally good at taking advantage of.

It was evident Friday once again. An offensive rebound by guard Payton Pritchard led to a Jayson Tatum three that tied the game. Baylor Scheierman drilled a three after an offensive rebound by Luka Garza for a five-point lead. The very next possession, Derrick White drained a trey after Scheierman hauled in an offensive rebound. Former Sixer Nik Vucevic hit a floater in the lane after grabbing a missed three by a teammate and Sam Hauser gave the Celtics a seven-point lead on a three after Tatum picked off an errant Sixers pass.

And that was all just in the first half. 

"One hundred percent," said Tyrese Maxey on if he feels the slight margin of error the Sixers have. "A turnover leads to a basket. An offensive rebound leads to a three. It's like every time. Every single time. And we did a hell of a job defensively guarding them, hell of a job in the half court. Everybody's fighting and doing a really good job. But it's like, offensive rebound, three ball. Turnover, three ball or layup. Box out (poorly), layup. When you play good teams, that's what it is. You have to be sharp, extremely sharp in the playoffs. You're seeing it."

No team is going to play the perfect game, particularly when it comes to the grind of the playoffs. In their win up in Boston, the Sixers played very well, but they were the ones who took advantage of the Celtics' miscues to pull out the win. Boston made a ton of them, and it was enough for the Sixers. If the Sixers make just a few, Boston pounces and the result is what it was on Friday.

"Last game (Game 2), they made a run and they cut it to two. We made every single play," said Maxey. "Like, they made a three, they come down next and they miss, we grab the rebound and we go down and score. They come down they shoot, they miss, we rebound. (Friday), we score, they come down, they shoot, they miss, they get the rebound again and they score. We turn the ball over, they score. It's little stuff like that where you can't have it. You can't have it. That's a hell of a basketball team over there. We are, too. It's certain mistakes that we just can't make."

Friday, the Sixers took an 85-84 lead early in the fourth quarter of the wildly exciting game. A goaltend gave the Celtics the lead. Consecutive turnovers by the Sixers upped the Celtics lead to five. The Sixers were able to cut the lead back down to two, but Jaylen Brown hit a pull-up jumper after, you guessed it, an offensive rebound. A few minutes later, a couple of driving passes by Paul George underneath to Andre Drummond led to dunks and a one-point game in favor of Boston. 

But Tatum calmly sank a three after a pump-fake sent a defender flying out of the way for a four-point lead with 1:57 to go and, after the Sixers cut it to two on a layup by George, Pritchard hit a step-back, going to his left three-pointer for a five-point Boston lead with 1:17 remaining.

Then came the ultimate dagger, a fitting ending of the night for the Celtics. After the Sixers had cut the lead to three, Vucevic missed a three with 37 seconds to go, but White got the offensive rebound and fed Tatum who drained a three-pointer for a six-point lead and, ultimately, the lead in the series.

"They ended up with 15 of them (offensive rebounds)," said Nurse. "It was a pretty tough rebounding game both ways. They just happened to capitalize a little more. They had 22 points off of second chance and we had 17. I think they hit four or five threes off of offensive rebounds, that's kind of doubly bad. It's a battle out there. We knew that that was kind of the No. 1 key coming into the series and we probably didn't do enough. I thought we had some really good stretches of it, but they got a couple of key ones there and obviously hit a couple tough shots there off the kick outs as well. Our guys played their butts off. It wasn't like they weren't giving effort to try and get those rebounds. They were trying the best they could."

And it was almost good enough. As the final result brought about disappointing feelings from the Sixers, the frustration of how Boston does it could be felt as well. 

"Yeah, yeah. It's tough," said Drummond. "Tonight, the offensive rebounds really beat us. The second chance points is really what got us. Other than that, we played a really great game besides those second chance points. We get those second chance points off the board I think we win the game."

"The attention to detail is really, really, really, really, really small," said Maxey. "I learned early on in my playoff career that the playoffs are broken down into single possession games. Every. Single. Possession. Matters. You don't want any of those possession to come back and bite you. Down the stretch, they aren't going to get too high or too low. There's certain plays where they all know what they're doing. They all know where they're trying to get to. They have that chemistry, they know what's going on. They've been together for a while. They've been through the battles, they've been through the wars. In our case, you have to fight like hell and push them to the limit. We can do that and we will do that."

And still, it might not be enough. Or in the case of Game 2, it will. The Sixers will try to be nearly perfect again on Sunday in Game 4, because that's about what it takes for them to beat the Celtics.
