I've seen some very low level college ball on YouTube where the pitchers don't have I/R mechanics.
I thought this was going to be a thread about NCAA/NPF pitchers who promote/talk about I/R mechanics (since that's what ambassador means). That actually would be a great list, since someone like Jennie Finch is great to model but not great to have as an instructor (unless she's changed her teaching). Would be cool to see which high-level pitchers actually preach what they practice. I suspect it's most of them these days.
Kind of hard to change your stripes when HE is your brand and at the core of all your tools, videos, and other revenue generating items.
Does anyone have a list or who is going to make a list of pitchers currently playing that use I/R? It would be nice to have for using with kids to compare motions.
