Um, the 2011 Mavs, 2013 Heat and 2014 Spurs were all new-age teams that didn't run primarily ISO ball..the 2012 Heat still had traces of being an ISO team(like the 2011 team), but weren't nearly as bad as a 90s team..
Statistically, Heat haven't been in the top 10 in the NBA in ISO % since 2012, despite having 3 great ISO options..even in 2012, they were barely in the top 10..if you exclude Wade, they would fall way further..
The Clippers weren't even close to being in the top 10 in ISO %

..
Among the final 8 teams in this year's playoffs, only the Thunder, Pacers and Nets would statisticially be labeled as ISO-oriented teams(I don't remember Washington's numbers, though, they could be up there)..
