Why the Celtics can cover

Guard Derrick White is a high-floor playmaker on the court. White can handle the rock to break down defenses with a sweet jumper to knock down his perimeter shots. The Colorado product averages 17.9 points, 4.1 rebounds, and 4.6 assists per contest in the playoffs. In Game 2, White finished with 23 points, six assists, and went 4-of-8 from downtown.

Guard Holiday (questionable) continues to be such a disruptive force on the defensive end. Holiday uses his high IQ in combination with awareness to make smart plays on both ends of the floor. The 33-year-old averages 12.4 points, 5.3 rebounds, 4.8 assists, and 1.4 steals per game in the postseason. In Saturday's win, Holiday racked up 14 points, nine rebounds, and three steals. See which team to pick here.

Why the Pacers can cover 

Guard T.J. McConnell is a pesky yet active playmaker off the bench. McConnell has a reliable mid-range jumper and likes to push the tempo to get out in transition. The 32-year-old thrives in doing all the little things and is averaging 11.6 points with 5.1 assists in the 2024 NBA playoffs. In his last matchup, McConnell had 23 points, nine boards, and six dimes.

Guard Andrew Nembhard is a calm ball handler and shot creator who owns good court vision but will push the pace to get out running. The Gonzaga product averages 14.3 points and 5.3 assists in the postseason. In Game 3, Nembhard recorded 32 points, nine assists, and made four 3-pointers. See which team to pick here.
