That's what I had to do to. I was damn near getting no hit all the time. Had to make some adjustments and now I'm doing much better. Still need to adjust the other way though as I'm starting to hit a little too well.
Yeah, it takes a while, but you'll find that sweet spot. I like to make my game more realistic. I can't stand having video game stats for my players. I want to have to work really hard if I'm going against someone like Kershaw.
