I have to totally disagree. They were running side by side at the EB near me, and the PS2 version was, well....nowhere near as nice looking as the xbox. It's simply not as clean or smooth. Things just look rougher around the edges. Maybe there's something specific to the LSU turf that the xbox got wrong last year, but textures overall are noticably better on the xbox.
Either way, graphics don't mean too much to me. I was a High Heat fan, so that should tell you how much more gameplay means than graphics, lol. I couldnt' tell you all the correct technical terms as to how the xbox has better graphics than the ps2, but it just has a sharper look. It would be difficult for the ps2 to have better graphics than the same game on xbox anyway, the xbox hardware is simply much more powerful.
