“I’AM LEAVING” NBA Small forward Jayson Tatum has announced that he is leaving the Boston Celtics due to…..

After the Celtics claimed their season-best eighth straight victory Saturday night, defeating the New York Knicks 116-102 at Madison Square Garden, Boston now has an eight-game cushion over the second-place Cleveland Cavaliers atop the Eastern Conference.

That is a bigger gap than the one between the West-leading Minnesota Timberwolves and the eighth-place Phoenix Suns (7 games).

But rather than applauding their league-leading performance through the first two-thirds of the season, the Celtics instead said they have higher levels to reach.

It’s just the way kind of the season has gone,” Celtics center Al Horford said. “We’ve kind of held our own, continued to work through things. Obviously the Sixers have injuries, different teams have different stuff going on, so that all goes into account.

“But I can just speak to we’re continuing to play good basketball. We’re really trying to play the right way.

I feel like [Celtics coach Joe Mazzulla] is really challenging us to continue to get better.

This is the stretch of the season where we can really take it to another level, and that’s what we’re trying to do.”

Asked what another level looks like for a Celtics team that has the league’s best-record (45-12), a massive lead over the rest of the conference and is one of only six teams since 1996-97 with a net rating north of 10 points per 100 possessions for the season (10.5, to be exact), according to ESPN Stats & Information, Horford smiled.

“That’s a really good question,” he said, “but I feel like we’re not where we need to be yet, and that’s a good thing.
