Are you sure that isn't an old poster? That seems to fly directly in the face of the rule changes announced earlier this year.
The committee approved two changes in Rule 5-11 related to falls and near falls. In 5-11-1, the shoulders or scapula of the offensive wrestler no longer must be inbounds to earn a fall. The committee agreed that wrestling should continue if the offensive wrestler’s supporting parts remain inbounds and no body part of the defensive wrestler goes off the mat. In 5-11-5, “unless any part of the shoulders or both scapulae of the defensive wrestler is inbounds” was eliminated. If wrestling is continuing during a match, near falls and falls will be awarded/earned regardless of the out-of-bounds line.
In a related rule, Rule 5-15-2b, c was changed as follows: “Near-fall points or a fall shall be earned while the supporting points of either wrestler are inbounds.”
“The committee agreed that offensive wrestling should be rewarded,” Hopkins said. “If wrestling is continuing, as allowed by current rules, and points for escapes and reversals are allowed, the ability to earn a fall or near fall should be there as well, with no deference to the out-of-bounds line.”
