Delay Warnings

[SC Official]

Why do some officials report a number to the table for a warning for delay? The warning is for the entire team, not the player who was responsible for the team receiving it. I've always just said "White, warning for delay" and told the coach what caused the warning if needed. Is there any reason I should be giving the number to the table?

Also, in NCAA-M, if a flagrant 1 foul is assessed to a defender for making contact with a thrower-in, does that count as the team's warning for player delay, as well? My gut was yes but I can't find anything in the books so I'm starting to think making contact with the thrower is separate from other throw-in plane rules.

I know in NFHS it would count as the team's warning if we had an intentional/technical foul for contacting the thrower/ball.
