Here's all the betting info you need for Saturday's clash.
The early money in Game 2 was on the Celtics and the under. When Game 3's market opened, the early coin came in on Boston and the over. The Celtics saw a minor bump from -2.5 to -3, while the total - which went under by one point in Game 2 - got a slight tick up from 206.5.
How hot is too hot? Despite coming out flat in Game 2 and digging themselves into a 13-point deficit going into the half, the Heat clawed back and outscored the Celtics by 20 in the third quarter en route to a 106-101 win.
Bettors have been waiting for Miami to regress to no avail. The team has covered 10 of the last 11 as it gets closer to a Finals appearance. There's certainly nothing fluky about the Heat's run, as they own the second-best net rating in the playoffs (6.8) behind only the Lakers.
Although the Celtics are 0-2 both straight up and against the spread in the series, there isn't much to suggest you should fade them. They lost the two games by a combined eight points, and you could argue they should have won - and potentially covered - both.
Boston turned the ball over a whopping 20 times in Game 2. Otherwise, the offense found some matchups it liked. The Celtics finished the outing with a 50% clip from the floor, which trumped Miami's mark of 44.4%.
