1) Basketball - only one free throw, but it’s worth two points or three points (if a 3 pointer). And 1’s are just added to the score, no FT needed.
2) Football - No more points scored kicking..No FG or XPT.
3) Soccer - expand the goals to make them wider and taller until the point that they score as many goals as an NFL team scores touchdowns.
4) Baseball - Get rid of home plate umpires and have AI call the balls and strikes.
