Very limited experience, 2017 at Arkansas - It looked to me that every role was up or grabs until the season started. It seemed Van Horn figured out who his guys were, and he'd give them some room to struggle through rough spots. If the rough spots lasted too long, he'd make a change. Unless the change lit the world on fire, he'd bring back his original guy, who'd have a different sense of urgency. I think the goal was let the players know it was their spot to lose and that mistakes/dry spells are tolerated as long it's not the new norm. I think this took some of the immense pressure off the players. Pitcher's were similar, but not as much tolerance. If you got into couple games where he just wanted strikes to let the fielders work, and it didn't happen - that might be it for the year.
