The stadium experience also needs improve. Many stadiums do not show controversial replays. That is really cheating the fans in the stands. It make the stadium experience less than the home TV experience.
Here's another excellent point. When I'm at a game, I wish I was at home watching whenever there is a close and controversial play being reviewed. I can think of several plays that have happened at the Rent where I have very literally said to my friends at the game "I wish I was at home so I can see what happened":
- G Davis "TD" grab in the endzone vs. Michigan
- J Baldwin's TD grab for Pitt in the back of the end zone (the famous J Todman 4th and 1 game)
- UNC's game-winning safety for a holding call against UCONN in their own end zone
- Temple's 2-pt conversion call
- Larry Taylor's fair catch
There are much, much more plays that I wanted expanded replays on the scoreboard but didn't get it. Davis' grab was shown a few times but it was only one angle (the angle that the entire stadium thought it was an easy TD...my friend watching at home said the TV replay showed another angle where you could clearly see the ball hit the ground).
If you want to not penalize fans at the stadium vs. at home, showing expanded replays with multiple angles/looks is a great start.
