The Patriots wore their silver helmets.
silver red and blue
The Patriots instead choose to wear the number 91 on the back of their helmets in remeberance of their fallen teammate Marquise Hill, who died over the summer of 2007 in a boating accident.
The Patriots changed the helmet logo in 1992. They went from Pat Patriot to the current Flying Elvis logo.
Silver and gold are too soft. They may have had silver or gold inlay...decorations.
Marquise Hill from the Patriots died, it's in remembrence.
The Patriots Pro Shop (on-line version) does not currently offer a silver dollar.
The Raiders uniform colors are silver and black.
Super Bowl XLVI (46) was held on February 5, 2012. It was a rematch of Super Bowl XLII (42). The New York Giants wore their dark blue and silver gray uniforms. (silver helmets) The New England Patriots wore their white and gray uniforms trimmed in red. (dark blue helmets) The Giants won again, 21-17, despite winning the NFC East with just a 9-7 record for 2011.
The 2007 Patriots are wearing circular stickers on the backs of their helmets with the number 91 on them, in honor of their teammate, the late Marquise Hill who was killed in a jet ski accident in May 2007.
New Century Silver is the silver/gray color on the flag. Check the helmet on the link below.
The Patriots did wear the 21 on their helmets in the 2007 season. They wore it for a single game. See the links below. They will take you to pics of players with the 21 on their helmet. The Patriots also wore the number 91 as a tribute to their fallen teammate Marquis Hill, who died saving someone else from drowning. So I guess the better question is why didn't the other 31 teams in the league wear an 91 sticker on their helmet?
