PREVIEW: The Boston Celtics, sitting at 47-18 overall, host the Oklahoma City Thunder, who boast an impressive 53-12 record, in what shapes up as a potential NBA Finals preview. Boston's defense ranks first in limiting three-point quality while maintaining the second-best turnover rate in the league, giving them structural advantages on both ends of the floor. The Celtics enter this matchup riding a five-game winning streak and have demonstrated remarkable momentum at home, rolling past several elite opponents. Meanwhile, Oklahoma City's defense ranks first in preventing rim attacks while forcing turnovers at an elite level, though their offense remains prolific at 119.7 points per game. The Thunder arrive in Boston fresh off a loss to Denver, snapping their home winning ways and costing them some momentum heading into this road contest. Oklahoma City compensates with the league's best low turnover rate, controlling the pace methodically while ranking second defensively against attacks at the rim. The Celtics come in as 4.5-point favorites according to current betting odds, reflecting their strong recent form and home court advantage.
