I could see taking our traditional jerseys and adding a very subtle, barely recognizable background hex pattern on the numerals ala Bama's combat uni's. No depth tricks to the cells that make them look like bubble wrap.
I thought they changed the rule.....To clarify uniform rules as follows: "Jerseys must have clearly visible, permanent Arabic numerals measuring at least 8 and 10 inches in height front and back, respectively, and be of one solid color that itself is clearly in distinct contrast with the color of the jersey, irrespective of any border around the number." This rule goes into effect for Football Bowl Subdivision teams in 2013. Football Championship Subdivision, Division II and Division III teams will have until 2014 before the rule becomes effective.
But I seem to recall seeing the honeycomb numbers last year at least once.
