Al Horford says the Sixers' identity in 2019-20 is going to be on defense and wrecking havoc on that end of the floor.

Horford and star big man Joel Embiid form a lethal defensive duo in Philly. For the past few years, Horford has defended Embiid really tough when the Sixers and Boston Celtics have played, so fans in Philadelphia are thrilled Horford is on their side now.

Al Horford signed a four-year, $109 million contract with the Sixers. This past season with the Celtics, Horford averaged 13.6 points, 6.7 rebounds and 4.2 assists while shooting 53.5 percent from the field, 36.0 percent from beyond the arc and 82.1 percent from the free-throw line.

The Sixers now have four elite defenders in Al Horford, Joel Embiid, Ben Simmons and Josh Richardson. Philly acquired Richardson from the Miami Heat in the Jimmy Butler sign-and-trade deal. Tobias Harris has the physical tools to be a stout defender. He just has to give more effort on a nightly basis.

Many believe the Sixers are the best team in the Eastern Conference after adding Horford and Richardson. Kawhi Leonard left the Toronto Raptors for the Los Angeles Clippers. Experts believe Philly and the Milwaukee Bucks will meet in the 2020 Eastern Conference Finals.

Horford signed with the Sixers for a chance to win a title. We'll see if Philly can accomplish its goal in 2019-20.
