Boley can't play the pass he's awful. His game is being a pass rusher. What that play was designed to do which was get pressure with the blitzer which the blitzer did forcing the QB to throw the ball early. Again it did just that. The play worked. Not luck it did what it was designed to do. No luck, just execution.
Giants ran plenty of zone blitzes when "God" aka Spags was running the defense.
