On Friday, the Cavaliers will be without three key guards in Ricky Rubio, Darius Garland and Donovan Mitchell. The decision to rest Mitchell could actually be a boost for the Cavaliers. He clearly was not himself in their victory over the Suns, as he shot 6-for-20 from the field. It also was a season low on their home floor with just 90 points. Denver’s showcase Thursday in a big blowout win lends to a letdown spot.
