My challenge would be, if our 9th man is always playable (with the exception of MP) then why would the expectation be that our 9th man this year isn't playable? Wouldn't past experience tell us that, according to your games played criteria, the staff actually has a 9th man on the roster they're confident in?Well, you're missing the point as it pretains to games played.
That's the biggest determinor of whether the player is getting onto the court. (the 3s comment was more so referring to skill set)
2021 Coleman Hawkins played in 25/31 games as the 9th man. That's 81%.
2022 Luke Goode played in 28/33 games. That's 85%.
2023 Ty Rodgers played in 33/33 games. That's 100%.
2024 DGL played in 28/38 games. That's 74%.
2025 Jake played in 32/35 games. That's 91%.
All of those guys, had the team had two of the top-eight injured, would've the coaches trust to get onto the court. Or if someone just wasn't playing well and we needed a change.
2026 Petrovic was the one exception: 19/37 games. 51%. That's likely a situation you'd like to avoid, rather than think it's a normality.
Therefore, I don't think it's crazy to say we need a playable 9th man. The idea that we always play 8 is pretty propaganda.
Another interesting stat about the 9th man on BU teams - only once has a player 9th or lower on the depth chart had a win share of 1 or greater. RJ Melendez in 2022 with a win share of 1. So, by that definition (which I admit the WS stat has its flaws), the 9th man is relatively inconsequential.
