Since the 2002 NBA playoffs, teams leading 3-0 in the conference finals have exhibited an intriguing trend. They have been 5-4 straight up, 4-5 against the spread, but most notably, 7-1-1 in favor of the over. This suggests that these situations tend to feature high-scoring affairs, indicating a favorable outlook for the over in this game.
Additionally, the Nuggets have shown some defensive vulnerabilities when playing their second consecutive road game in the playoffs. Coupled with their potential relaxation on the defensive end due to their commanding 3-0 series lead, it could result in a more open game with increased scoring opportunities.
Considering the Lakers' desire to avoid a series sweep, they are likely to focus on pushing the pace and maximizing offensive efficiency. Also, the Lakers have shown inability to limit the Nuggets so far this series.
Given these factors, it appears highly likely that game four between the Lakers and Nuggets will exceed the current total of 224.5. The historical trend of teams in a 3-0 series lead favoring the over, combined with the Nuggets' defensive struggles in specific circumstances and the Lakers' offensive mindset, all point toward a high-scoring contest.
