The Philadelphia 76ers made a major move Sunday night by reportedly agreeing to send superstar forward Jimmy Butler to the Miami Heat in a sign-and-trade. The 76ers' biggest move of NBA free agency was revealed just minutes later.

Veteran forward/center Al Horford, who spent the last three seasons with the Boston Celtics, is taking his talents to the rival 76ers, according to ESPN's Adrian Wojnarowski.

Horford declined the player option in his Celtics contract earlier this month to become an unrestricted free agent, and for him to get a four-year deal worth $109 million at 33 years old is a great outcome for him. 

The 76ers' starting lineup next season could shake out like this:

PG: Ben Simmons
SG: Josh Richardson
SF: Tobias Harris
PF: Al Horford
C: Joel Embiid

This is a very good five-man rotation for Philly, who also lost veteran guard J.J. Redick to the New Orleans Pelicans in free agency Sunday. The 76ers, with Horford in the fold, likely will be the favorite to represent the Eastern Conference in the 2020 NBA Finals.

The Celtics have now lost two of their top players, Kyrie Irving (Brooklyn Nets) and Horford (76ers), to Atlantic division rivals early in free agency.
