Miami are 0-3 and every loss has the same shape: opponents bombing threes, Miami losing the glass, and their own shooting going cold. Dallas look depleted on the injury list, but most of those names never played this season, and the two creators who matter are back. Giannis in the paint is the clearest edge either side has. The question is whether that one edge is enough to open a real margin against a Dallas side that runs.
Giannis scored 35 against Minnesota and 36 against Detroit. Without Lively or Aldama, Dallas have only Gafford and Washington to meet him, so expect paint touches and free throws. The catch is fouls: he fouled out after 25 minutes at Charlotte, and Flagg's drives are exactly the kind of play that draws them.
On the other side, Miami's starting five of Mitchell, Thompson, Wiggins, Giannis and Adebayo has been outscored by 30 in 31 minutes together. Miami's threes have gone 8 of 33, 15 of 51 and 13 of 35. Their comebacks have come from the bench group, not the starters.
Dallas lost by 16 at home to San Antonio, and that game is what the market keeps pointing to. But that team had neither Kyrie Irving nor Cooper Flagg. Irving is off the injury report and Flagg has been upgraded to probable. Lively, Aldama and Biberovic have not appeared in a box score all season, so their absence is already in Dallas's numbers. Naji Marshall's illness is the only new loss, and it takes away a secondary ball-handler.
Dallas create in transition: 28-15 in fast-break points against San Antonio and a 22-6 run at Indiana off turnovers. The glass is roughly neutral, since both sides have lost the boards to bigger teams.
Expect Dallas to threaten early runs against the Miami starters, and Miami's bench to push back in the second half. That shape keeps the margin tight. That's why I'm siding with Dallas, taking the points.
