Kristaps Porzingis will likely miss this entire series, and the Celtics need to be careful against a physical Cavs team that is capable of playing bully ball. Cleveland's Jarrett Allen missed the last three games against Orlando with a rib injury, and he's listed as questionable tonight. Among playoff teams, the Cavs posted the second-worst offensive rating thus far in the postseason (only Pelicans were worse). However, for all of their offensive struggles, the Cavaliers are at the top of the charts in several defensive metrics. Two of the three regular season meetings between these squads stayed under the total. Boston's series with Miami combined with Cleveland's series with Orlando combined to go 7-5 to the under. The Celtics' offense will have to make some adjustments without Porzingis. Cleveland's offense will have to make adjustments...everywhere. Don't expect to see many fireworks in Game 1.
