My comment was general as to differences between 40/43 foot eras in Kentucky softball, not directed at Montana Fouts. The most dominant pitchers in 2017 can't put up numbers like pitchers put up 10-15 years ago. I also think the talent level is far better now as well.
As far as Fouts, when you mix in the lack of competition it becomes even more difficult to figure. Last year she had a .15 ERA for the season and 3.09 at state tournament. She gave up more hits at state than all season combined. She's clearly a big talent, but she has not been challenged playing high school softball. That seems pretty clear.
