No predictions, too superstitious. I expect most of if not all books to have BOS favored (we are -225 right now on ESPN Bet).
As many have said, Luka + Kyrie vs. Tatum + Brown should be fairly even but favor BOS. It may be close or could bounce back and forth game to game. Tatum is only 29% from 3 in the playoffs. He will need to do better than that (and I think he will). Luka is about 34% from 3 for the playoffs. BOS will need the big guns to perform (as will DAL if they are to have any chance).
I see it coming down to what guys like Jones + Washington + Green + ????? can do as compared to Holiday + White + Pritchard + Hauser. On paper, we should win this grouping, at least when White and Holiday are on the floor. I know these guys don't match up one for one by position, but this to me is the secondary scoring grouping. The guys that will need to make shots when the primary guys are double teamed. Jones and Washington play starter minutes, like White and Holiday. They have been pretty good in the playoffs.
As to the bigs, they have Gafford + Lively + Kleber, we have Porzingis (hopefully) + Horford + Kornet/Tillman. Again, on paper, we should win this grouping also. Kleber gives them a different look than Gafford and Lively but he has been hurt. Horford and Porzingis can provide a level of scoring and spacing that DAL can't get from their guys.
