What exactly are you implying about a 10 yard restraining line? The fifteen yard kick minimum be extended to twenty five? Tweaking the onside kick could pretty much eliminate it as a standard play. Please elaborate.Well, the one thing I haven't seen addressed here is player safety. The NFL and NCAA have instituted rules to make the onside kick harder and safer.
In sixman you can overload a side completely and have a 20 yard sprint, with the intent of someone blowing up the receiver to force a turnover. Plus in most cases even if the return man gives himself up, he still gets hit.
I would favor a 10 yard restraining line and the kicking team can not release until they kicked the ball. I have had players every year knocked out of the game and miss one to three weeks due to concussions recevied from onside kick coverage.
