Add ClutchPoints as a Preferred Source by clicking here.While the New York Knicks are the defending NBA champions and they should raise their championship banner with the confidence that comes with winning the franchise’s first title in 53 years, the Philadelphia 76ers appear to be in a position to steal their thunder.After adding Jaylen Brown and LeBron James in the offseason, the Sixers are the team that nobody will be able to take their eyes off of as the season gets underway. Many observers believe this dynamic team — that also includes Joel Embiid, Tyrese Maxey and VJ Edgecombe — will be the best in the league.When it comes to flat-out talent, the Sixers certainly will be able to make a great argument.

Yet, it happened and the Celtics split up the duo of Brown and Jayson Tatum that had previously won an NBA title. The Celtics got George and draft choices in return, but it is clear the Sixers made the bigger splash.It didn’t stop there as they also got the biggest free-agent signing in the offseason when James made his decision to go to Philadelphia.
