Every rebounds prop the books have posted for Zach Collins of the Chicago Bulls, with the NBA game log the number is drawn from, game by game and split by where and when they played.
Calculated by the ParlayBuilder Prop Engine.
Every figure on this page is counted from official NBA box scores, one row per game actually played. No projections, and a game the player missed is absent rather than scored as a zero. Where a hit rate is compared with the live price, it is first pulled toward that price in proportion to how thin the sample is, so three-for-three does not read here as a certainty.
Past performance does not predict future results, and Parlay Builder does not accept wagers, hold funds or settle bets. This is measured history and a price, and what you do with them is your decision.
You must be 21+ (or older, where your jurisdiction sets a higher age) to bet. If gambling stops being fun, call or text 1-800-GAMBLER (1-800-426-2537) for free, confidential help.
It loads live at the top of this page, with the best price across the major US sportsbooks beside it. It is deliberately not printed into the page itself: a line moves through the day, and a page that hard-coded one would keep telling you a number the book no longer offers.
The hit rate beside the line answers exactly that, measured against the exact line on offer over the games in the log below. The game count it is drawn from is printed next to it, because a rate without a denominator is not a measurement.
That depends entirely on the price, and this page will tell you when the answer is no. A prop only clears the research bar when its hit rate, pulled toward the price for a short record, sits ahead of the break-even the current price implies, with at least ten games behind the rate, a B grade or better and a price a book has refreshed recently. Most props on most nights clear none of that.
