some meathead has definitely thrown too much before entering a game.. i bet some of those buffoons require a coach/staff member to watch them, even after years of playing pro ball. it may even be strategic - a mind set they need to be in to perform well in front of crazy people screaming at them.
and, just to point out... one way is exclusive and the other is inclusive. the status quo allows the upset person to turn off warm-ups, which is essentially equivalent to their perspective of it, and those that want to manage it get to use it. if it were changed, the people who enjoy that will no longer get to experience that pleasure.
heck, i turn off $$$ for draft picks.. in my world the league exerts its leverage and squashes that nonsense
