(update) The cavs are still discussing whether or not to ask Danny for more. I'm willing to bet they don't want Danny to call their bluff and pull the offer. Noob GM doesn't know how to complete a faithful trade

The Cavs are still mulling whether to ask Boston for something else besides Isaiah Thomas, Crowder, Ante Zizic, and Brooklyn's No. 1 pick for Irving because of Thomas' injured right hip that could keep him out an extended period of time this season.
As of Monday afternoon, two sources told cleveland.com that there was nothing new to report on those deliberations, with one source saying the Celtics were still waiting to hear what (if anything) extra the Cavs wanted for Irving.
Cleveland could accept the deal as it was originally constructed, ask Boston for more -- such as another young player like second-year man Jaylen Brown or rookie Jayson Tatum -- or for an additional draft pick. A league source expected the Celtics to resist the Cavs' request, especially for a significant piece like Brown or Tatum,
unless "Danny Ainge feels like (the Celtics') doctors ruined Thomas."The source expected the trade to ultimately be completed because of the value of the Brooklyn pick -- a potential lottery selection -- and Crowder's versatility as a defender and his team-friendly contract. Crowder has three years left on his deal worth $6.8 million, $7.3 million, and $7.8 million, respectively.
Training camp starts in one month, and onlookers believe the Cavs don't want to have to try and trade Irving again, while Boston would be left without a reliable point guard if Cleveland voids the deal.
