Tonight’s slate takes us to TD Garden and Crypto.com Arena for a pair of pivotal Game 2s in the opening round. With rotation patterns starting to solidify and injury reports shifting, the betting value lies with the players whose roles are expanding under the postseason whistle.

By using our Pick Labs Ladders Tool, we can identify which players are statistically primed to shatter their projected totals. Below, we break down two ladder opportunities for Tuesday—spots where the math suggests a massive edge on alternate lines.

NBA Role Player Parlay for Tuesday, April 21

  • Kelly Oubre Rebounds Ladder
  • Reed Sheppard Assists Ladder


Kelly Oubre Rebounds Ladder

76ers vs. Celtics | 7:00 p.m. ET

With Joel Embiid officially ruled out for Game 2 as he continues his recovery from an appendectomy, the Philadelphia 76ers are missing 11.0 rebounds per game from their lineup. That creates a vacuum on the glass that must be filled by the supporting cast if Philly wants to avoid a 0-2 hole heading back home.

Kelly Oubre was one of the few Sixers who showed significant fight in the Game 1 blowout, grabbing 7 rebounds in 31 minutes. As Nick Nurse tightens the rotation for a must-win Game 2, Oubre’s energy and length will be required on the floor for extended stretches.

Our Pick Labs Projections show a clear edge on his rebounding milestones. We are projecting a 67.3% chance for Oubre to hit at least six boards, providing a 15.9% edge against the market price of -106 — and for those looking to climb the ladder, the 7+ (+175) and 8+ (+311) rungs also show double-digit edges as Philly looks to match Boston’s intensity on the interior.


Reed Sheppard Assists Ladder

Rockets vs. Lakers | 10:30 p.m. ET

The Houston Rockets struggled offensively in their Game 1 loss to the Lakers, but Reed Sheppard was a bright spot as a playmaker. Sheppard logged a massive 36 minutes and dished out 8 assists, proving he can handle the ball-handling duties on the big stage.

The big news for Game 2 is the expected return of Kevin Durant, who is a game-time decision after missing the opener with a knee contusion. While KD's return might cut into Sheppard's usage slightly, it actually improves his assist quality. Having an all-time floor spacer like Durant on the receiving end of passes makes every potential-assist more likely to convert.

Even with Durant back in the fold, our Pick Labs Model still sees substantial value in Sheppard’s playmaking floor. We project a 74.8% probability for him to record at least three assists tonight, giving us a 12.2% edge at -167.

We’re attacking the 3-5 assist range, with the 4+ (+144) and 5+ (+308) rungs offering enticing plus-money value for the Rockets' young  guard.


NBA Role Player Parlay for Tonight's Playoff Games

  • Kelly Oubre 7+ Rebounds (+175)
  • Reed Sheppard 4+ Assists (+144)

Parlay Payout: +563

If you combine these two props from our top edges, you get a parlay with a potential a payout of +563.

This is considered a long shot for the reason, and you should treat it as such. However, we are showing a nice edge at that price — with our Pick Labs models projecting a 28.4% chance of this parlay hitting, while +563 implies only a 15.1% chance.
