Why impact metrics and on/off data don’t rate Jaylen Brown highly
Honestly, the conclusion is pretty easy to reach once you look past his volume scoring.
This really shouldn’t have eluded people for as long as it did. Like, you had people throwing out a decade’s worth of empirical data because they couldn’t address their own biases. Well, onto my points…
He’s a turnover machine
Since 2023, he’s in just the 46th percentile for TO per 75 and cTOV%. He’s also in just the 15th percentile for sTOV%.
He’s also had just a 1.4 A/TO ratio in that span, abhorrent for a perimeter player.
Costing your team possessions while giving extra possessions to your opponent is a surefire way to bleed value.
cTOV%: Turnovers adjusted for offensive load. Essentially, it’s TOV% but for higher volume players.
sTOV%: Turnovers committed during scoring attempts.
He doesn’t create extra possessions
Since 2023, he’s in just the 49th percentile for steals, the 38th percentile for blocks, the 51st percentile for offensive rebounds, and the 40th percentile for deflections.
All this stems from a lower motor. For a player with his physical tools, you’d figure he’d be much more active on the court.
He doesn’t maximize his team’s offensive possessions
Since 2023, he’s in the 42nd percentile for FT% and the 44th percentile for 3P%. He’s in just the 14th percentile for 3PAr as well, so he’s living off of a diet of long 2s.
He’s in the 59th percentile for TS% and the 14th percentile for potential assists per min.
All in all…you have a player who costs his team possessions, gives his opponent more possessions, doesn’t create extra possessions for his team, and is a mediocre shooter/playmaker. So yeah, pretty easy to see why he’s not a high-impact guy.
