I heard this quote from a well known pitcher the other day, she was being interviewed during one of the college games and she was asked about masks... she said (paraphrasing)..."i'm not a fan of them, I feel like if you wear a mask then you are less likely to work hard enough to make sure you hit your spots and avoid leaving it fat and having a hitter drive it"....This is that bias we talked about and this was a really well known pitcher, I just forgot her name.
That may not be the dumbest thing I've ever read, but it's up there.
