Game 2 Cavs vs. Knicks prediction

My Cavs vs. Knicks prediction is Knicks -6.5 (-110). The Knicks completed the largest postseason comeback in franchise history in Game 1. Expect that momentum to carry into tonight and provide a boost for the Knicks, while bringing down the Cavs.

NBA experts and I are in lockstep that the Knicks cover the spread. This expert quote is another reason I expect New York to win comfortably and extend their series lead to 2-0 tonight.

“I cannot trust Kenny Atkinson to adjust. There are clear answers on film for the Cavs, and they showed flashes of them in Game 1. But Atkinson simply has not demonstrated an ability to push the right buttons in these playoffs; that’s why it has taken the Cavs 15 exhausting games just to get to Game 2 of this series.”
