Yeah I'm not saying I'm actually running the slider at zero, just that it maybe should be an option if you were completely indifferent to which RB got the rush.
I just don't want my FB to run the ball. He's to block or catch. I'll put in FB rushes if I want him to rush.
I've played with the slider for two seasons now and some games, it's just my RB's running while others (at the same setting) my FB gets an equal share of the rushes. That's in the low-mid-thirties.
I'm simply suggesting a way to say "However we do this, I'll choose the play if I want my FB to run the ball."
He's not in the RB part of the depth chart, he shouldn't run the ball, unless it's a designated FB rush (or WR Jet Sweep, if that was to ever be implemented)
