They should be the same or very similar. If you have a medium Fall Court Trad Polo, I'd go for the same size in the Barricade Polo. Unless you're very tall and skinny, it will run a little bit long too (all Adidas collared Polos seem to be that way).
Slight differences in fit tend to run between differently cut shirts using different materials. Eg. Barricade Polo v Edge collar-less Polo (a great shirt IMO).
