Hard to critique it because I am sure they aren't done putting it all together, but I don't miss the betting lines constantly scrolling. The graphics look simple and I love that. Let the game tell the story. And I don't know what has changed, but when it was Fan Duel and Bally's there was a constant problem with the audio going out of synch and being 4-5 seconds ahead of the video. I'd have to exit out and go back in, but it would always happen again. I watched for about an hour and change yesterday and that did not happen, so I hope that continues.
One thing that's weird is when you watch older games on cable channels or you tube - in the era before they had the score on the screen (that was a Fox innovation), it's very frustrating. I think the people that replay those games should include an overlay. Just a basic one (Score and Inning or score and quarter/clock) When Fox first got football they made some great changes - like the first down line on the screen was another (some people still think the players can see that). I do wonder if they could actually put a laser line on the field for the players and refs could see where the line actually is. Seems like there could be something electronically they could do that could trigger whether the ball has crossed the line.
