## Tonight's Slate

- SA @ OKC

## Pick 1: Julian Champagnie (PF) — SA @ OKC (Away)

*Worst DvP categories: 3-Pointers Made (1st, 3.0 allowed)*

**Top DvP mismatch tonight.** Julian Champagnie draws the kind of defense scoring props are built for: OKC's scoring defense against PFs ranks bottom-tier.

## Pick 2: Isaiah Hartenstein (C) — SA @ OKC (Home)

*Worst DvP categories: Assists (3rd, 4.9 allowed)*

Points over is the primary angle. SA's scoring defense against Cs ranks bottom-tier, and Isaiah Hartenstein is the C who walks into that softness tonight.

Home court adds the small bump that turns a "consider" into a play.

## Pick 3: Shai Gilgeous-Alexander (PG) — SA @ OKC (Home)

*Worst DvP categories: Blocks (3rd, 0.7 allowed)*

Shai Gilgeous-Alexander draws the kind of defense scoring props are built for: SA's scoring defense against PGs ranks bottom-tier.

Home court adds the small bump that turns a "consider" into a play.

## Honorable Mentions

- **Stephon Castle** (SG, SA) — OKC 5th in rebounds allowed to SGs.

Keep Stephon Castle on your radar - OKC is exploitable in rebounds, even if the full mismatch isn't as wide as the picks above.

## Before You Lock

Check the [Defense vs Position dashboard](/nba/defense-vs-position) for full 1-30 rankings at every position and stat. Confirm lineups before tip - if a starter is resting, the backup won't move the needle the same way. DVP is more powerful when the player is also in good recent form.
