What Are PRAs, PAs & Stocks in NBA Prop Betting?

Betting on the overall performance of a player in a given game has become a popular option for NBA bettors.
The easiest way to do that is through combo props, which you'll often see referred to by their initials:
- P+R+A = total points, rebounds and assists
- P + A = total points and assists
- R + A = total rebounds and assists
- P + R = total points and rebounds
- Stocks = total steals and blocks
So if you see someone bet Russell Westbrook under 30.5 PRAs, they're betting on him going over or under 30.5 combined points, rebounds and assists in that game.
It works exactly the same as a points prop, but includes multiple statistics, so the line will be higher.
Here's how it looks at DraftKings. They're listed under player props, and all combo props should be near each other.
Why Bet Combo Props?
Bettors like combo props because they offer a way to bet on a player's entire output in a single game, which is generally tied to usage in the NBA.
If you expect a player to see more minutes than sportsbooks are accounting for, you might bet the over on his P+R+A prop. Because it features all three stats, that player can overindex on points but underperform on rebounds and still hit the mark. You're just counting on that player to be on the floor and contribute.
That's an oversimplification, of course. The props are priced to reflect all three stats, and there's no notable edge by blindly betting combo props vs. single-stat props.
How Do They Price These Props?
It's not too complicated — sportsbooks project each individual statistic, then combine them. A P+R+A line should be very close to that player's individual props, all added up together.
In the example above, Joel Embiid's P+R+A prop is listed at 46.5. His individual props were:
- 30.5 points
- 12.5 rebounds
- 3.5 assists
Same with James Harden:
- 24.5 points
- 8.5 rebounds
- 9.5 assists
That's 42.5, matching his P+R+A prop.
What About Stocks?
Stocks — steals + blocks — are becoming a niche favorite.
These props will be listed low because steals and blocks are harder to come by, and juiced accordingly.
Evan Mobley's stocks line is listed at 1.5, but you need to lay -160 ($16 wins $10) to bet the over. The under is plus-money at +120 ($10 wins $12).
Stocks props are popular for players who are active defensively and disrupt the opposition in different ways.
