At the game last night, I really didn't notice much difference watching the Flames from the stands, but I don't like the changes to the Oilers uniforms. I didn't like the darker shade of blue and they got rid of the white line between the blue and orange on the numbers, which makes them a little harder to read from a distance.
Also, the little air holes in the numbers make the numbers look faded because you can see a bit of the white jersey through them.
Another thing I noticed watching some of the highlights from last night, it doesn't seem like other teams lowered their logos on the front of the jersey as much as the Flames did. Still not a fan of that.
