🎯 Thunder vs. Celtics score prediction: Thunder 115, Celtics 113
One of my trusted projection models has Oklahoma City to win outright in Boston, 113-112, suggesting this is a coin-flip matchup. There is value on the road team, as I predict the Thunder will beat the Celtics by a final score of Thunder 115, Celtics 113.
Best bet: Thunder +3.5 (-110 via BetMGM)

🏀 Best Payton Pritchard prop pick: Under 2.5 3-pointers ⭐⭐⭐⭐⭐
Best odds: +124 via DraftKings ($10 to win $12.40)
Payton Pritchard’s scoring prop is trading at 12.5 after being 13.5 or 14.5 in recent games. That tells me the market knows he won’t be as involved, despite his 3-point prop still trading at 2.5.
Pritchard has hit three triples over his last two games on 12 attempts, scoring 11 points during that span. I project 2.5 3-pointers for Pritchard against Oklahoma City’s No. 1 defense, meaning there is value in this +124 price at DraftKings.

🏀 Best Chet Holmgren prop pick: Over 1.5 assists ⭐⭐⭐⭐
Best odds: -135 via bet365 ($10 to win $7.41)
Oklahoma City center Chet Holmgren is getting his legs under him, playing 55 minutes in a back-to-back against the Denver Nuggets earlier this week. He recorded only two assists in those two games, which makes me even more inclined to take the Over on his assist prop tonight.
Holmgren has finished with multiple assists in three of his past five games, dishing 12 dimes over that span. I project him to finish with 2.7 assists in Boston, so don’t be surprised to see this line move before tipoff.

🏀 Best Jayson Tatum prop pick: Under 9.5 rebounds ⭐⭐⭐
Best odds: -137 via Caesars ($10 to win $7.30)

Jayson Tatum’s rebounding prop has dropped to 8.5 at some of our best NBA betting sites, indicating where this line might close. The Boston forward might have difficulty getting to double-digit rebounds in a game featuring as much length as this Thunder-Celtics matchup.
Tatum is averaging 8.9 rebounds per game, finishing below this mark in eight of his previous 14 outings. I’m interested in the plus-money price on Under 8.5 boards, but this Caesars discount is worth scooping up before then.

🚑 Thunder vs. Celtics injuries
Here are the latest injuries for tonight's Thunder vs. Celtics matchup, which will update in real time.
The biggest absence for tonight's game is on the Oklahoma City bench, with big man Jalen Williams out with a hip strain. Alex Caruso is one of the two key players - along with Boston's Kristaps Porzingis - listed as questionable with an illness. These will be ones to watch as tipoff approaches.
Jaylen Brown (probable) and Jayson Tatum (questionable) also have injury designations, but the latest betting lines suggest they'll suit up tonight against the Thunder.
