I was under the impression that the DPE was for this season only - meaning even if the Cs use the full $8.4M allotted to them this year, that contract would fully come off the books this offseason and they would be left with only the MLE and Vet Min options.
Is it possible that what 'they' meant was that Cs will give a player the full $8.4M DPE this year (massively overpaying them compared to other teams) and then sign them for the minimum next year by 'combining' those contracts to give a solid Aron Baynes-like contract for two years?
This wouldn't necessarily net them a top-level starter (just over $5M/yr - not including what said player is making this year in salary/buyout), but he would need to make the full MLE from another team next year to make it worth it and he would also get their money up front. For the Cs - they save a LOT of money next year when they are going to likely be tax payers.
If I am wrong about how the DPE works, I apologize in advance. Thanks for the inside info about how the Cs are looking to use it! Ainge is certainly always pushing for an angle
