The stadium thing is another thing all together. They just had to build 2 versions of the stadiums, it's not a template thing. That being said, I agree about the jerseys. For all the small minuscule details that they put in the game its hard to understand why the jersey details receive so little attention. Even last year when they put time into they daily jersey schedule for teams as well as adding jerseys that had been left out, they still had numerous errors with the jerseys.
But hey, this is a very early build so maybe this is something that eventually gets adjusted. So far they seem to be addressing small details that have been issues for a while.
