Throwbacks are only the last two home games of the season, vs NE and BUF. All remaining road games are almost certainly going to be white over aqua. The DEN game will be aqua over white. Im holding out hope that TB is aqua over white also, but it seems that they'll be (stupidly) locked in to the Week 1 choice of white over aqua, even though the game was moved way back in the season.
The throwback is our official alternate, and can be worn twice. The Orange was a Color Rush uniform, only to be worn on Thursday night.
