Dylan Harper has the 3rd-best rim FG% (65.5%) of any guard in the playoffs since 2000.
*min. 80 attempts*
He is a rookie.
Stephon Castle has the 4th-best (64.9%) – and at 21 years old, is the second-youngest on this list behind Harper.

The volume is equally as impressive as the efficiency
Harper also ranks 3rd-highest since 2000 in rim FGM per 36 minutes:
1) Donovan Mitchell ’18 – 5.51
2) Ja Morant ’22 – 4.78
3) Dylan Harper ’26 – 4.45

Very exciting times for @PlayProphetX !
I’m confident a lot of people will be surprised to see the immediate impact ProphetX has in the CFTC-regulated environment – especially the non-everyday sports bettors.
Excited to follow along closely. 📈

“steel canister that holds and insulates three stacked 12-ounce cans of beer”
“scientifically proven to leave consumers with no hangover”
“Everyone wins. More beer. Zero hangover.”

Starting to see a trend here …..
WCF:
OKC (SGA on): -35
OKC (SGA off): 9
SAS (Wemby on): 62
SAS (Wemby off): -36
Finals:
NYK (Brunson on): -13
NYK (Brunson off): 20
SAS (with Wemby on): 10
SAS (with Wemby off): -17
Jun 9
Wemby is averaging 29-10 in the Finals on 59% TS with 5 stocks per game. The Spurs are 10 with him on the floor and -17 with him off.
The G2 late game fiasco notwithstanding, he's putting together a nice first Finals against a team that is constructed to stress his weaknesses.

Do the Spurs win in 5 if Wemby checks Brunson 1v1 for the rest of the series?

Are we officially done with this debate?
Harper has been one of the best guards in the world for a couple weeks now
Rutgers, with Harper 5th overall pick Ace Bailey, did not come close to making the NCAA Tournament last year

How many current NBA players could hop on a 16 seed in the tournament and win the national championship?

Getting a lot of angry replies here
1 seed Florida was a 35.5 point favorite against 16 seed Prairie View A&M this past March Madness
You add Wemby, SGA, or Giannis to this 16 seed and they are still a very significant underdog vs. Florida
Let alone win the entire thing …

Very cool OTC transaction between @galaxyhq and @arca
Makes for the 2nd clear win-win transaction since the Myles Garrett trade earlier this week
Today, we're launching institutional OTC prediction markets trading through our Global Markets desk.
Hedge funds, family offices, and other institutional clients can now access prediction market liquidity at sizes and with a level of discretion suited to institutional scale.

Would not be surprised if KAT sleeps in his parents’ bedroom for the next 3 weeks

I wonder if Chet Holmgren turns his basement lights off and then runs up the stairs cause he’s afraid Wemby might be behind him

Djokovic was 280 to beat Alcaraz in the 2026 Australian Open Final (26.3% chance)
Djokovic is now 420 to win the French Open (19.2% chance)

A cross-platform early payout / exposure netting feature would be a huge win for PMs
Market makers could post significantly more volume with less capital tied up - delivering highter total volume & better liquidity for the exchanges
@antonin_parrot is this in the works?
May 27
New Episode of the podcast out where @Sports__Proj and I discuss this question along with some other important topics in the space. Main topic is stuff we learned from sports books that helps in PMs. Kalish v. Kalshi heavily covered in news.

SGA, regular season:
From 0-5 feet: 5.9 FGA (69%)
From 15-19 feet: 2.5 FGA (54%)
SGA, WCF:
0-5 feet: 3.5 FGA (64%)
15-19 feet: 4.8 FGA (42%)
It’s almost as if the Spurs have an 11-foot alien under the hoop drastically affecting SGA’s shot selection and efficiency.

Knicks advance to the NBA Finals for the first time since 1999
Zero signs of celebration or fulfillment from Jalen Brunson after the game
He’s always had 1 goal in mind and 1 goal only
13 Jun 2024
Jalen Brunson on “1A” discussions:
“I believe that I can help my team win…I’m not dying for that recognition to be the person who needs all that attention for just himself. I want the title champion. That’s all that matters.”
