I don't know a good analogy to put this in. It just wasn't the greatest separation. It wasn't the greatest thing that could've happened to us as a team, a bond. We were at war with those guys [Miami]. To go with the enemy, that's unheard of in sports. Well, it's not so unheard of. It's damn near common now.
The mindset we had. The guys on our team. You wouldn't do anything like that. It makes you question that series in the Finals … Who were you for? You didn't bleed green. People think we had a messed-up relationship. It's not the greatest. But it's not just me. I called and reached out to a couple of other vets and asked them what they wanted to do with the situation. They told me to stick with what we got [without Allen].
Rondo emerged alongside that trio, making four straight All-Star teams from 2010-13, and they would play together for five seasons. The Celtics made the playoffs every year that group was together, winning an NBA title in their first year and winning the Eastern Conference title in 2010.
Spears noted Allen has been "estranged from Rondo, Pierce and Garnett" in the years since he left the Celtics. He signed a three-year deal with the Heat to play alongside LeBron James, Dwyane Wade and Chris Bosh, helping that group win a title in 2013.
Pierce told Spears last November the "biggest disappointment" he had regarding Allen's departure was not receiving a return phone call before Allen decided to sign with the Heat.
Rondo said he would've given Allen—who didn't offer a comment to Spears in the story—an invite if members of the team wanted him to.
Allen sat out the 2014-15 and 2015-16 seasons while deciding if and where he wanted to play. The 18-year veteran officially retired from the NBA on Nov. 1. Garnett retired last September, and the two will presumably go into the Basketball Hall of Fame together as part of the 2021 class.
