According to Caron Butler, LeBron James and Dwyane Wade are the reason the Miami Heat lost to the Dallas Mavericks in the 2011 NBA Finals.

Flash back to almost a decade prior. The Heat were on the verge of completing their first season with their “Big Three” trio of James, Wade and Chris Bosh. Miami appeared to be on their way to winning a title as they were on the verge of taking a 2-0 series lead. In Game 2, the Heat held a 15-point lead midway through the fourth quarter before Dirk Nowitzki led a Mavericks comeback and an eventual 95-93 victory. Dallas would go on to win the series in six games.

Butler — who sat out that series due to an injury and is a former teammate of Wade's with the Heat — remarked that Miami lost that series due to their two stars.

Via Adam Wells of Bleacher Report:

“When we beat OKC. To me, I felt like this was the hardest team to overcome and I felt like we would win after we beat them. The Lakers didn't seem as dangerous that year, we beat them and we beat Portland. OKC didn't know any better because they were too young. I really felt like our percentages were high because I didn't think Miami had it figured out yet. I remember Brendan Haywood looking at me like: We gotta get one before they could figure it out because LeBron and Wade didn't know who was Batman and who was Robin.”

In that series, James was seen deferring often to Wade in the fourth quarter. It got to a point where it became such an issue that James was blasted in the media for being passive.

While the Heat did fall short in the 2011 NBA Finals, they eventually figured it out and won two consecutive Finals in 2012 and 2013.

However, as Brendan Haywood noted, the Mavs had to beat the Heat before they figured out who was Batman and Robin. And because they did, they have a championship to show for it.
