I love that when the USA loses we immediately attack the rules.
I say we suit them up like the fencers.
Electrodes and wires throughout the singlet and shoes.
An electronic barrier along the mat to signify the boundaries.
Use the same eagle-eye technology that they use in tennis to show if a ball is in or out.
Let the computers determine in-out of bounds.
Let the computer determine the takedowns.
Keep the human element out of reffing.
That is, until someone figures out how to hack it.
