Cavaliers at Celtics OddsShark Matchup Report

Boston Celtics

The home and road splits for this Boston team over the last two months have been quite extreme. With their two losses in Cleveland, the Celtics fell to 1-8 SU and 2-7 ATS over their last nine road games. Conversely, the Celtics have won and covered in each of their last 10 home games while going 13-1 SU and ATS over their last 14.

The difference in the team’s energy and performance is abundantly clear on the court between home and away games, making Boston very dangerous in Game 5 despite their two straight losses.

The Celtics have excelled as a home underdog this season going 10-1 SU and 11-0 ATS in their last 11 games as one per the OddsShark NBA Database.

Cleveland Cavaliers

LeBron James was never going to go down without a fight in the Eastern Conference Finals, and his Cavaliers showed plenty of fight with back-to-back wins of 116-86 in Game 3 and 111-102 in Game 4.

James scored 44 points in the Game 4 victory as the Cavaliers jumped out to a 34-18 lead in the first quarter and never looked back. Kyle Korver also made an impact off the bench with 14 points in each of these two wins. Cleveland is 8-4 SU and ATS in its last 12 trips to Boston.

Wednesday’s total is set at 206 points. The UNDER is 10-3 in Boston’s last 13 home games against Cleveland.

With the way that Boston has played on the road and the killer instinct James has at home, it’s likely that the Cavaliers will win Game 6 at home. Whether that game is a potential series clincher or just to force a Game 7 in Boston will come down to how the Celtics perform in Game 5.
