Two-time NBA champion Ray Allen recently opened up about the main difference between the two title-winning sides he had an honor of being a part of. The Hall of Famer described how the 2008 Boston Celtics were much different than the 2013 Miami Heat.

According to Allen, it all boiled down to the depth and the experience of the Heat side:

“The Miami team was deeper. From top to bottom it was just vets,” Ray Allen said on a recent appearance on James Posey's The Posecast. “It was a problem that Spo had because he had so many players he can go from James Jones to Mike Miller to Shane Battier. You look at the roster everyone can play and contribute. On our roster in Boston, once you left PJ [Brown] and Sam [Cassell] everyone else was like Big Baby [Glen Davis] who was a first-year player. We had [Brian] Scalabrine]. We had [Tony Allen]. We had Gabe Pruitt. A lot of young players who haven't been on the stage.”

As Ray Allen described above, that Miami roster was stacked. Allen himself was at the tail end of his career at that point, already playing in his 16th season (he retired after Year 17). The sharpshooting 2-guard was actually the second-most experienced player on that team, behind only veteran Juwan Howard, who was playing in his 18th year.

With the 2008 Celtics team, however, Allen was still in his prime. He was coming off one of the best seasons of his career, averaging 26.4 points per game with the Seattle SuperSonics. Allen saw his production dip significantly once he arrived in Boston due to playing alongside the likes of Kevin Garnett and Paul Pierce.

One things is clear, though. Both of these sides were successful in making their respective marks in NBA history, and Ray Allen was a huge part of this, including hitting one of the most iconic shots in NBA history.
