Howard will team up with Simmons and Joel Embiid in Philadelphia after leaving NBA champions the Los Angeles Lakers for the 76ers via free agency.
An eight-time All-Star, Howard won a title alongside Lakers superstar James in Los Angeles and he is relishing the opportunity to play with former number one draft pick Simmons in Philadelphia.
Simmons – an elite defender and creator with unrivalled pace – averaged 16.4 points, 8.0 assists and 7.8 rebounds per game last season before injury cut short his campaign as the 76ers were swept by the Boston Celtics in the opening round of the playoffs.
"Ben Simmons is a young LeBron... I love the way he plays. I love how unselfish he is, and how mean he can be to other teams, and that's important," Howard told reporters on Wednesday.
"When you have your point guard coming down, dunking on people, flexing, getting big rebounds, talking trash, doing all those things, it drives you to want to be better.
"He has an opportunity to be one of the greatest to ever play the game, and I'm glad I have the opportunity to actually give him some things that can help him along the way."
Howard arrives in the city of Brotherly Love with one thing on his mind – delivering the 76ers their first championship since 1983.
Much has been said about franchise pillars Embiid and Simmons, and their compatibility as the 76ers prepare for life under new head coach Doc Rivers, who replaced Brett Brown.
When Embiid and Simmons play, the 76ers boast a 119-65 win-loss record, per Stats Perform. But without one or both, they greatly suffer (67-94), Embiid's physicality in the paint and Simmons' superior defensive skills vital in Philadelphia.
The 76ers average 111.7 points, 107.5 opposition points, 47.4 rebounds and 26.4 assists per game with Embiid and Simmons involved, a clear improvement compared to when one or both miss a game – 106.7 points, 109.4 opposition points, 44.5 rebounds and 25.0 assists.
Philadelphia also have a superior field goal percentage (46.9) when Embiid and Simmons both play, with the 76ers shooting just 45.3 per cent without one or both. Opposition numbers also go up in their absence – field goal percentage (44.3 to 46.2) and three-point percentage (34.1 to 35.5).
"There's a lot of things," Howard replied when asked why he thinks the Sixers – who also recruited Seth Curry and Danny Green – can win a title. "You have two great young stars in Ben Simmons and Joel Embiid, I'm going to start there. Those guys, to me I watched when Joel lost [to the Toronto Raptors in the Eastern Conference semi-finals in 2019] and how bad it hurt, he just cried, and I know what that feels like. I've been in that moment before where it's like, 'Man, I gave everything I had. I put it all on the line and I came up short.'
"It doesn't sit well with you, it stays with you for a really long time. So with him I know he has a fire inside of him, and we've all seen glimpses of it all year, and I think this is the year where it's about being focused. I see focus in him, I see focus in Ben, and that's where it starts with our two best players.
"Then you look at the rest of the guys on our team, they've all been hungry, they just never knew how to win. And I think by adding a guy like Danny Green and myself, we just fresh off of winning a championship, and I think we all know what it takes to really get to the next level.
"And I think this is a really great opportunity. You have a coach always talking about winning, how important it is to win, and you have some players who just want it. I think this year with the focus this team will have and the drive that we have to be successful, this will be our year."
