just needs decent judges!
Use the 'yes or no' system. 4 yes's is a UD, 3 and a no is majority, 2's each is split with the winner decided by however they do it on these crappy talent shows. If all 4 judges buzz in because they're bored of a fighter (Mayweather, Klitschko etc) then it gets stopped immediately.
Replace Jim Gray and Max Kellerman with Ant and Dec for the post-fight interviews and it's sorted.
If people want boxing on terrestrial tv again..
