even when they are successful. Seldom do they achieve even a first down and the interception and incompletion rates make them bad plays in my opinion....unless the defense lines up 1 on 2 with a second defender 20+ yds. deep...and how often does that happen? Even if that were the case, I am not sure that the single defender can be blocked on a pass play until the ball is caught so a penalty risk may be in play also. If I never see another one it will be too soon.
