This is the best suggestion to address the issue I remember seeing. That said, I still have some misgivings about the idea of the "Go no matter what" option. Maybe more discussion would help me out. I agree that should definitely be much riskier in general if it was an option. If it was implemented I'd hope the wishes to be able force runners to go would be replaced here by complaints that speedy & good stealing runners forced to go are being thrown out too much by weak-arm catchers.
As it is now the in-game steal option seems to be just turning on the green light and it is up to the runner to "decide" whether or not to try. How often do managers tell the runner to go even if he is being hounded and kept close and cannot get a good jump? I would think occasionally, but not very often. Any ideas? I know it can be frustrating when a runner does not try to steal, but I worry about this turning into something a human player can exploit with too little penalty.
