Monday Player Prop Best Bets
Below you’ll find my official plays on the player prop market for Tuesday. These are the ones that make the VSiN Pro Picks page and count towards my season-long record.
Onyeka Okongwu Over 18.5 Points (-106) vs. Bulls
Bulls at Hawks – 7:30 pm ET
Okongwu had 23 points in 40 minutes of action against the Bulls on Sunday, and that performance wasn’t a fluke. Chicago is the worst defensive team in the NBA when it comes to guarding around the rim, and this is also a bottom-10 group when it comes to defending above-the-break 3s. Well, those are two areas of the floor that make up 62% of Okongwu’s scoring. He can do a lot of damage from within 10 feet, but he can also step out and knock down triples. Okongwu is also going to continue playing big minutes for Atlanta, as Kristaps Porzingis’ illness is keeping him from taking the floor. With that in mind, it’s a no-brainer to fire up Okongwu to score at least 19 tonight.
Pascal Siakam Over 22.5 Points (-113) vs. Bucks
Bucks at Pacers – 7:30 pm ET
Siakam had 25 points in 37 minutes in a hard-fought loss against the Celtics last night, so there’s a chance he’ll be a little tired this evening. However, Siakam should still be able to take advantage of this meeting with the Bucks. Without Giannis Antetokounmpo, Milwaukee is worse when it comes to defending at the rim. This is also a team filled with poor individual defenders, which is why they’re miserable when it comes to defending in isolation. All of that should play into Siakam’s hands, as he’s one of the better individual bucket-getters in basketball. There’s a reason Siakam had 32 points against the Bucks back on November 3. And while I’m not quite expecting another performance like that, I do think 23 points is well within reason.
Cooper Flagg Over 28.5 Points + Rebounds + Assists (-120) vs. Nuggets
Nuggets at Mavericks – 8:00 pm ET
Flagg is averaging 37.2 combined points, rebounds, and assists over the last five games. He has also gone over his PRA total in five of his last seven home games. Tonight, Flagg will be going up against a Nuggets team that is playing without Aaron Gordon, who is one of the few players on the roster that has a shot at defending the rookie. That makes it hard to imagine this being a poor offensive showing from Flagg, who always seems to chip in a good number of rebounds and assists. Flagg actually had 24 points, eight rebounds, and two assists in a road win over the Nuggets on December 1. That said, he has already taken advantage of this matchup by filling up the box score. Why can’t he do it again?
Stephon Castle Over 1.5 Made 3s (+130 – 0.5 units) vs. Thunder
Thunder at Spurs – 8:30 pm ET
Castle’s odds to make at least two 3s seem a little off tonight, so I’m sprinkling something on the second-year pro to knock down multiple triples. Castle went 2 for 5 from 3 in a win over the Thunder in the Emirates NBA Cup semifinals last week, and that’s a little hard to ignore here. Oklahoma City is so good defensively that teams often jack up 3s to get higher quality looks at the rim. Well, we could see some of that from San Antonio tonight, and Castle isn’t going to be shy. He probably won’t force up a ton of 3s, but I can see him taking five or six. He has actually taken at least five 3s in four of the last six games. With that type of volume, I’ll take my chances at +130.
