Best NBA player prop picks on Wednesday: Anthony Davis, Mavericks, Over 10.5 rebounds (-136) Jaylen Brown, Celtics, Over 11.5 combined rebounds + assists (+105) Jarrett Allen, Cavaliers, Over 12.5 points (-124) Click here to play these NBA props with the latest FanDuel promo code, which gives new users $300 in bonus bets if your first $5 bet wins: Anthony Davis, Mavericks, Over 10.5 rebounds (-136) He was 32-21 over this line between his time with the Lakers and Mavericks. With all of his height, Wemby doesn't make the Spurs a good rebounding team (-4 per game on the road last season). In home games Davis was especially big on the boards with a 12 rebound average (16-9, 64% over). In three games vs. the Spurs he averaged 13 and went over all three times. Take advantage of a fresh, motivated Anthony Davis to do at least his average work on the boards. New users receive $300 in bonus bets if your first $5 bet wins, plus three months of NBA League Pass free with the DraftKings promo code. Jaylen Brown, Celtics, Over 11.5 rebounds + assists (+105) We are projecting him for 12 in 34 minutes but given the absence of Jayson Tatum in the high profile matchup vs. Joel Embiid and the 76ers, we could see Brown getting closer to 40 minutes. Anfernee Simons clearly isn't as good a player as Tatum but he's a 20+ point per game scorer, if the Celtics want him to be, and he'll provide plenty of assists for Brown. Embiid may be playing but he's not a great rebounder for a star center and the Celtics are projected to outrebound Philly despite Brown leading the team with just 7.3. Without Tatum, Al Horford and Krystaps Porzingis, they'll need Jaylen Brown to have a career year on the boards. Use the latest BetMGM promo code to bet this prop and get receive up to $1,500 in bonus bets if your first bet loses as a new user. Jarrett Allen, Cavaliers, Over 12.5 points (-124) We are getting a line based on last season's road average of 12.7 which was considerably less than his 14.2 at home. Mitchell Robinson is out, newly acquired Yabusele is too small and Karl-Anthony Towns is too vulnerable a 1:1 defensive player to keep Allen from scoring in the paint, especially off of dunks and offensive rebound putbacks.
