Philadelphia 76ers newcomer Al Horford admits that playing against the Boston Celtics in Sixers' opener on Wednesday night will be ‘weird,' per Philly Inquirer's Keith Pompey.

“It's going to be weird for me, different facing my former team. It's probably as good as a scenario as it can be. First game of the year we'll do it. Yeah. It's definitely going to be different. It's not just another game. It's a big game given the rivalry, Philly and Boston.”

Horford spent the last three seasons playing for the Celtics. He was one of the team's most reliable veterans, and he mentored some of the members of Boston's promising young core. The Cs tried to re-sign Big Al this summer, but he decided to take his talents to Philly and join the Sixers.

At 33 years old, Horford is at that time in his career where he wants to give himself the best chance to win a championship. And at this point, he felt like the Sixers have the best shot at helping him win his first ring.

The Sixers are touted as one of the best defensive teams in the league heading into this season. Four members of their projected starting five are at least 6'9 in height, so they will definitely cause problems to the rest of the NBA.

As for the Celtics, losing Al Horford was definitely a huge blow for them especially since they were also left by All-Star guard Kyrie Irving. But they were able to recover just fine, as they have added Enes Kanter to replace Big Al and another All-Star in Kemba Walker to replace Uncle Drew.

So the new-look Celtics team will be ready for the Sixers on opening night.
