is pulling a pitcher with a no no intact breaking an unwritten rule? someone needs a ball in the back
Yes, and fans just can't handle that sort of stress. There'd be a lot more team no-hitters if pitchers were replaced as needed rather than keeping the starter in there

gassed hoping for a statistical nicety.
In other words, everyone (managers, players, fans) gets hung up on the no-hitter and forgets about just winning the game and pacing pitchers for the full season.
