The Cleveland Cavaliers enter their December 31 matchup against the Phoenix Suns aiming to protect home court and build momentum in a tightly contested Eastern Conference. Cleveland (18‑16) has shown the ability to produce explosive scoring outputs, led by Donovan Mitchell, who continues to average elite points per game while contributing across rebounds and assists. Jarrett Allen anchors the paint on both ends, giving the Cavaliers a reliable interior presence that can alter shots and control rebounds. Cleveland’s offense thrives on pace, ball movement, and perimeter shooting, allowing them to generate efficient looks even when defenses tighten. The team’s ability to get to the free-throw line and convert from mid-range adds another layer to its scoring versatility, making them a difficult opponent to contain when firing on all cylinders. Despite offensive prowess, defensive inconsistencies remain Cleveland’s Achilles’ heel. The Cavaliers have struggled to protect the paint consistently and close out on three-point shooters, which has allowed teams like Phoenix to exploit gaps and accumulate points quickly.

Their home ATS record of 6‑11 reflects these lapses, as the team can dominate for stretches but often falters when required to sustain effort over four quarters. Injuries and rotation changes have further complicated consistency, forcing the coaching staff to rely heavily on bench contributions and adapt defensive schemes in real time. For this matchup, the Cavaliers will focus on leveraging home court advantage and Mitchell’s scoring to set the tone early. Defensive discipline, controlling the glass, and limiting turnovers will be critical in countering Phoenix’s balanced offensive attack. If Cleveland can execute in transition, capitalize on high-percentage opportunities, and maintain energy throughout, they can neutralize the Suns’ momentum and remain competitive. While Phoenix’s recent win streak and offensive versatility present a formidable challenge, Cleveland’s scoring depth and interior presence provide them a pathway to a tightly contested and potentially high-scoring affair in front of their home crowd.
