What is the wrist band on a NFL official used for?

The wrist bands actually have an elastic loop attached to them.  This is the important part.  The refs place the bands around their fingers to keep track of the downs.  Also, the umpire, the guy behind the linebackers, will use the band to remember the previous spot of the the ball.  For example, pinky finger= left hash, ring finger=left goal post, middle finger= middle of field, etc.

Black band is usually to grieve and pray tribute to a player or personality\nIt is also sometimes worn to show protest. For example, a few teams visiting Zimbabew wore black armbands to protest against the dicator Mugabe

Its a sweat band/ arm band / wrist band. Its a fasion, works like a sweat band, and is comfortable... (black and white match with anything so thats why they wear those colors)

When I worked in HR, I had a lady come in wearing a criminal ankle bracelet.  You know the once for used for keeping track of criminals on house arrest? Well she told me :" oh this thing on my ankle?  I only have to wear it for six more months and I only have to wear it because my stupid a** friends turned me in.I don't use drugs anymore, but if you need me to do a drug test , I would like it if you could wait a week or two"---and my boss overrode me too telling me when need to give everyone a second chance.  Six months later she was arrested walking out of work and last I heard was doing 5-10 in prison!

I personally say no, as I find most of them to be funny and entertaining, but Walter Payton and Barry Sanders just handed the ball to the ref after they scored.  That is class!\nDon't forget, NFL stands for the No Fun League.  The NFL has been implementing rules to limit player expression for years.  They outlawed skull caps a couple of years ago as well as bandanas.  Every player has to have their socks pulled up a certain height and players aren't allowed to celebrate former players on the field.\nWhen Johnny Unitas passed away, the following week, Peyton Manning wanted to wear the high top shoes like Johnny U always wore.  This wouldnt give Manning any sort of advantage, but the NFL said no because it didnt fit into the dress code.\nJake Plummer wanted to wear a patch on his jersey and helmet for an entire season for fallen friend and former teammate in college (ASU) and pro (AZ Cardinals) Pat Tillman.  The NFL said no because they want to constantly promote the NFL over any individual player.\nEver see a current coach get dressed up and wear a suit on the sideline?  Not anymore.  20-30 years ago, coaches were allowed to wear whatever they wanted, but now the coaches have to wear something with their teams emblem on it.\n\nThese rulings are the most depressing thing about the NFL.

Alot of players use those bands for extra grip when they carry the ball.  But thats mostly running backs.  Others use them to make their biceps look bigger.

Well each team goes to a professional organization to get their helmets designed and prepared.\nThey get draft-designs and choose the best pf the designs.\n\nOfcourse, the officials of NFL should approve the designs.

It's a computer graphic that only the viewers see.  It's similar to the graphics that are used in the NFL to highlight the first down marker.

it's purpose it to mark the end of the play and where the ball should be placed for the next play.  That location then becomes the line of scrimmage.

The player that has a yellow band is the captain of the team...\n\nThey use it 2b differenciated from the others

It is my understanding that the NFL has been requiring players to wear helmets for many years now.  They are standard equipment.\n\nPS. Patriots rule.

For a QB they may have a long pad that goes from their wrist to almost their elbow.  That is for the QB to play calls.  It includes all the plays for the offense.

Well American football wears pads and rugby they only wear helmets. They both have footballs also called (Pig skins). But rugby kicks the ball and throw it to there players to score but Americans Throw it too there players until they can score

They have been calling it alot this year.  It further prevents defensive players from making a tackle and just laying on the opposing player running down the clock.  \n\nGood rule, but in this instance it was a bad flag.

I don't think anyone's ever worn zero.  Up until a few years ago, when numbers were becoming scarce due to retiring numbers, every position had a sset range of numbers that were allowed by the NFL.  WR wearing numbers in the 80's for example.  The league's loosened up on that now, so who knows what numbers you'll see in the future.
