How to bet them
Target stolen base overs when paired with a slow-delivery pitcher and weak-armed catcher (per the book's framing: SB is a pure matchup play). Target hits and runs overs; fade HRs and TB overs. Runs prop benefits from any lineup that gets them to second base.
Where they fail
Elite pop-time catchers (Contreras, Realmuto tier) erase the SB prop entirely. Against sinker-ballers who keep the ball on the ground in big infields, their hit ceiling compresses to singles that don't drive anyone in.
