Those are good ideas thanks. I noticed that Fangraphs does SBA/CS for Catchers and just SBA for Pitchers. Can kind of eyeball it that way but it's hard to tell unless you see some big outliers. For example, Syndergaard has given up 12 steals (the most in baseball by far) in just 30 innings.
But take tonight for example, Myles Straw batting leadoff against Mahle/Stephenson. Mahle has given up 4 steals on the year and Stephenson has 13SB and 6CS. I guess that would be considered kind of neutral?
I guess the other problem with trying to chase steals with Straw is that he can't hit righties but he doesn't get many steals off of lefties. Hmmm
