If some use this and say the 6 rule means C's can trade up to 10 and do so by just using 16 and 33 it can't be a good chart. It is unlikely but not necessarily a bad deal for Heat.
Here is what 16 and 33 get you the last few drafts vs 10.
2014 Payton for Nurkic(16) and then your PG choice of Dinwiddle, Clarkson or Russo Smith.
2013 McCollum for Muhammad or Greek freak for SG at 16 and Cann or Muscala.
2012 Rivers for Big of choice Zeller, Jones, Sully and then shooter late Middletown. Or even Green and Crowder were there second round
2011 Fredette(10)/Klay (11) "shooter" for pick pf Vucevic, Harris, Shump, Butler and more guys its nuts how many good guys late then in second get your shooter in Parsons.
So hindsight is 20/20 but there were a bunch of good combinations going by the metric.
