Looking at the morning line and digging into the stats, the New York Knicks enter as clear favorites. They boast a dominant 19.8 Net Rating and a 56.0% total rebound percentage this postseason. If you are tracking situational betting trends like I am, you’ll see that the Knicks have been incredibly reliable in this spot: the over has hit in 4 of their last 5 games as a favorite, and they are 5-1 against the spread (ATS) after a win over their last 6 games overall. But don’t count the Cleveland Cavaliers out just yet. Carrying a solid 2.7 Net Rating and grabbing 50.9% of available rebounds, they know how to battle in the trenches. The Cavaliers have proven they can handle elite competition, going 4-1 against opponents with a winning record and an impressive 4-1 against top-10 scoring defenses over their last 5 games. If you’re looking for a wager we can all rally behind, both of these squads have trended heavily toward high-scoring affairs. The over has hit in 4 of the Cleveland Cavaliers’ last 5 playoff games, perfectly mirroring the New York Knicks’ recent over trends.
