I see no difference. The rules were enforced in both cases. No, Stevens didn't need to push off in order to score, but that doesn't change the rule, which isn't based on whether the ball is caught or not. The ref was close to the play. He saw the clear infraction and he threw the flag. He had no choice under the rules currently in place. What thousands of posts have now said is that the ref in this case should have ignored the rules of the NFL, and not called a clear penalty because a score was involved. Such an action by a ref might get applause from the fans of one team, but the ref would and should get discplined if he ignored the violation.
