Would love to see the Jaguars incorporate the Bengals-like helmet concept and adopt a predominantly dark gold jersey.
The reason for the helmet :
There are many teams who have a logo-type helmet.
There are many teams who have a horns-type helmet (vikings, eagles, rams)
So there would be nothing 'wrong' with the Jaguars sharing the pattern-type helmet (bengals).
Here's a sample provided by someone else of my Jaguars idea...
And here's me messing about. Don't have a jersey design truly in mind to make the helmet and jersey-pants-socks blend thematically.
