Here's a slightly different DAL-CHA idea (with ORL added) that might be a more palatable swap for all the parties involved ---
*DAL gets Hayward ... sends THJ/Bertans
*CHA gets THJ or Bertans (their choice) ...sends Hayward + pick 13
*ORL gets THJ or Bertans (whichever is left) + pick 13 ...sends nothing
Mavs - No added salary - Mavs actually get a 5M savings on payroll
CHA - Doesn't have to give up PJW, still gets about 15M savings + THJ [for GH/13]
ORL - Gets pick 13, priced with a smaller salary to absorb (about half the size of GH)
