I agree with you, CLH (but I will make allowances for extenuating circumstances). Wednesday I was working a JV game. Sub comes in, table buzzes us, sub isn't in the book. I tell the coach, he says, "Yeah, he is, but he's under number 23. That's my bad." We signal the T, shoot the throws, move on with the game. That team lost by 2, but the T was hardly the deciding factor.
At the lower levels, us just giving the T becomes a learning experience for the coaches as well as being just takin' care of business.
