Agreed, but there is also going to be a lot of noise in SB numbers. The pitcher matters, the runner matters, catchers only get about half the games for a team. With Jeffers you're talking about 38 stolen base attempts in 2022. Nobody would expect OBP to tell the whole story after 38 at-bats. With that small amount of data you're probably better off with a stopwatch measuring pop time and estimating.
Even for his career it's 103 stolen base attempts. You can get some information about batting after 103 at-bats. Then we have the unknown of how Jeffers would do if he stopped setting up with a leg out and set up in a crouch instead to stop the running game when there is a fast baserunner.
