The only difference between the aqua and white designs is that the new jersey cuts require the stripes fit on that gore panel rather than on a full sleeve. Those new cuts didn't exist in 2003. Last year one of the Dolphins ( I think it was Maxwell) actually wore a full-sleeved aqua throwback (what nike sells to the public) in the 9er game. If there was a white version now, it would have the sleeve pattern the same as the aqua. Technically, it is a different jersey from what was worn in 1966 due to the sleeve cut... but I digress. I personally wanted the throwback to be stripeless like the Dolphins wore in 1970-72, which to me was their BEST jersey.
BTW I have waited to get a throwback because I keep hoping the cut sleeved version will become available to the general public... but I am afraid nike will never let that happen.
