Over the past 33 NBA selections, Cimini is 22-11, returning more almost $800 to $100 players. He is also on an amazing 38-16-1 run with his last 55 against-the-spread picks involving the Celtics, returning almost $1,800 to $100 players.

Cimini knows the Celtics are scoring 105.8 points per game in the series, while the Heat are averaging just over 100. Boston has put up better numbers almost across the board, owning a four-rebound margin and shooting 5 percent better from the field. Jayson Tatum had 30 points and Jaylen Brown scored 20 on Friday, but Brown had just two points in the second half. Derrick White came up big off the bench, scoring 11 of his 22 points in the fourth quarter.

He also is aware that Jimmy Butler can take over like he did Friday, when he scored 47 points. The Heat shooters are bound to get hot. They are shooting just 31.5 percent from three-point range after leading the league during the season at 37.9. Victor Oladipo is almost 10 percent below is season average (31.8-41.7). Miami typically plays strong defense, and it ranked fourth in the NBA in opponent scoring (105.6 per game) and field-goal percentage (44.7)
