Nice job updating the site for the NFL, congrats', it looks awesome. But I don't remember this being done before, Dan or Tom or Lummox or Deadron or anyone, are you gona' be doing this more often? Perhaps with the NHL, NBA, or maybe holdiay themes like christmas or something? Of course, then you would have to take into account religion so that probably won't happen. Either way great job it looks good.
Oh and BTW, I've seen some BYONDer's complaining about the team you chose, why not make it Byond Oriented? The helmet could easily have the word byond on it and the goal posts could stay relatively the same. Just an idea.
