Seems like the plan was to use derek jones as the dime, hense starting hecht as well as him rotating with hecht. Which worked out great. And as jpan commented, when kyrie went down we saw a lot more of that set which worked great.
A big reason why we are able to pull that off as well is Hallet but especially Exume. Exume may well end up being the steal of the draft.
If Kyrie is down for any length of time though I think we need to look hard at bringing in an imp Lber. Though Kongbo is listed as a Lber on the roster. Its possible if he gets healthy he could fill a tweener role.
