Retro jerseys I believe. And regardless, its close to a final build which means it more than likely won't get looked at, let alone fixed due to the tweaking on the "exciting" pro tak system they have now that apparently fixed the blocking.
I dunno.... the more vids I watch of 10, it looks exactly like I'm watching 09. Only difference is that its slowed down, takes 9ppl to bring down a WR, and there is somewhat of a pocket for the QB to sit in. Other than that, GAMEPLAY wise... its the same game.
