Hey! Someone else who works in TV!
1. NJCAA doesn't have to play by NCAA rules but to make life easy on those involved it generally does. There's one difference I know off the top of my head: NCAAM now allows players to dunk during warmups. NJCAA does
not.
2. Rules
. My one pet peeve is when announcers say a foul is on Player X before seeing the official's signal and then they say, "Actually, they changed the foul to..." The official didn't change the foul. The announcer got it wrong. Just admit it.
3. See NCAA.com
4. See answer #3...but the big differences off the top of my head would be:
*NCAAW = 4 10-min qtrs, NCAAM = 2 20-min halves
*W = 2-shot bonus on 5th foul of qtr, M = 1+1 bonus on 7th of half, 2-shot bonus on 10th foul of half
*W = HC can be granted a timeout when ball is live, M = HC
cannot be granted a timeout when ball is live
*W = no set penalty for players who fake fouls, M = players who fake fouls can be penalized (I'm an NCAAW's official so I don't know what the penalty is)
*W = restricted arc is 3 feet, M = restricted arc is 4 feet
*W = team granted a timeout can advance ball to 28-foot mark in last 0:59.9 of game, M = no rule
Obviously there are others but these are the ones that come to mind.
5. Silence is golden. Knowing when to be quiet is just as important as knowing when to speak.
