In football the computer will tell exactly where the ball is. That will help those punts that went out of bounds. It would analize everything.
Baseball would be really cool. Considering balls and strikes. We would have different type of HBP: if the ball grazed the uniform without hitting the player its a ball.
Tennis the computer will be a great help with those lines. Hockey and the hockey stick swing. The time of pentaly and when a player could get on the ice exactly.
Basketball there is a huge amount of data to watch.
Crew human refs they suck. Time to get into 2004 and beyond and while we are at it maybe we could put some implants in those players to make them jump higher and hit harder and be bigger.
I'd like to see the Olympic events judged with modern optics also. The pole vaulters could vault and they would be judged on how high they actually went. If they vault 18' they wouldn't only get credit for 17' 9" because that's where the bar was set. Long jumpers would be judged for the actual length of their jump and not penalized for their toes being 1/2 inch further back than their competitors when they left the ground. Runners and swimmers could be judged starting from the time their nose broke the plane of the starting line. Trying to time the start would no longer matter. There are tons of improvements that could be made to find out who truly is the best. I'd love to see a track meet like that. If promoted well it could be a very popular event on TV as well. It'll never happen though. Sigh.</p>
