Many people. You're asking who had those numbers in over a decade's time.
What are the crossed-out numbers greater then 1 called
I don't know, but a 49er means a celebration after a win. Maybe that is why they have a 49 on their helmets.
It represents what number that player is
composite numbers
For players that died in the offseason or during the year.
The "gold" helmets are part of their throwback jerseys of old.. same reason why their home jerseys are black with gold numbers and letters instead of the normal white.
The Univ of Syracuse wore orange helmets with blue numbers for two seasons in the 2000's (I believe 2005-6, though I can't find verification of this.) Prior to that they were plain orange on the sides. Its helmets currently have an "S" logo on the sides.
The Broncos wear the numbers 27 and 29 on their helmets to represent the jersey numbers of two of their players who died recently. * 27 is for Darrent Williams a corner back who was killed in a drive by shooting in Jan. 07. * 29 is for Damien Nash a running back who had a heart attack and died while playing in a charity basketball game in March 07.
List the numbers from 2 to 100. Rows of 10 work well. Cross out all the multiples of 2 that are greater than 2. This will be the rest of the even numbers. Go to the next number that isn't crossed out (3) and cross out all of its greater multiples. Proceed in this fashion. Next up will be 5. You can stop when you get to fifty. The numbers that aren't crossed out are prime.
