I AM saying LnP is justified. Wresting is a martial art just as much as BJJ or Muay Thai, should we take those out of MMA?
Its called MMA for a reason, learn to sweep from the botton or to stop a take down or stop fighting.
And why should LnP win you a fight┐ In BJJ, also part of MMA, the guard is a neutral position. If nothing else happened in the "fight", then LnP should lead to a draw, not to a win.
