I see what you're saying but there are some differences. The chevron pattern is different, and doesn't extended onto the sleeves. No stripes on the ends of the sleeves. Texture pattern on the blue and some shadowing and white on the chevron stripes. Red Canterbury logo. Different arm sponsor. Maybe not enough of a difference overall.

Anyway the blue collar is growing on me already, and with the white shorts it essentially keeps the team's classic look. I think the new stuff looks great. I've started buying supporter gear since we went back to the original colours.
