Your (and your kins) problem is you’re so adverse to anything “old school” even if it makes sense.
There’s no doubt analytics are vastly important to judging pitching. Being able to break down a pitcher’s ERA and WHIp etc to determine luck and try to predict future performance are no double critical and anyone against it is stupid.
But I can even tell you from watching my son and his teammates pitch for 10 years...
Some days you have it and some you dont. It doesn’t change at any level but obviously the guys that are most consistent are the most successful.
Obviously there’s other things at play like going through lineup second time. Like you said, there’s times where someone looks great and then blows up, it happens. And you should prepare for it but when you have a guy with everything working, you should ride it at least a little if your alternative that you’re handing ball off to in gas can that’ll prob be on 6 teams in the next 8 years. If you’re a team with a really good bullpen, maybe it makes sense to not ride the hot hand and in that case, I could support giving the ball to a guy you can trust with good reason. AJ Cole is not that guy. I’ll take the percentages with the hot hand all day
