NFL could approve profound change to the extra point - DenverBroncos.com (blog)
But if any are ratified, the play would undergo its boldest change since the NFL added the two-point conversion in 1994. The first, submitted by the New England Patriots, moves the line of scrimmage for kicked extra points back to the 15-yard-line. It succeeded at reducing the conversion percentage from 99. 4 percent over the 2010-14 seasons to 94. 3 percent during the trial period, although last summer's sample size (141 extra points) was considerably smaller than the 6,153 attempts over... This mimics a college rule, and would end the NFL practice of having a play blown dead the moment a kick was blocked or a player on the defending team possessed the football. Either team could score one point on a safety. So, for example, if a player on the defending team intercepted a pass in the end zone, crossed the goal line, then doubled back into the end zone of his own volition and was tackled, the offensive team would get one point from the play. The final proposal, made by the Philadelphia Eagles, also moves the placekicked extra point scrimmage line to the 15, but shifts the two-point conversion spot from the 2-yard-line to the 1, which is designed to offer greater incentive to go for two. If the two-point spot is moved to the 1, it could benefit teams with dual-threat quarterbacks. Source: www.denverbroncos.com
