I would not consider this a trend, because we'd been steady at around 42% allowed since the Seattle game, then with Sunday night's game, the Giants' 11 of 16 performance brought it up to 45.1%. We'd held the Giants to 5 of 13 in the first game, so it looks like they made the right adjustments.
More importantly, though, keep an eye on drive success rate. It's a much better stat than 3rd down conversion % because it takes all downs into account when measuring how well an offense moves the chains. (The defense ranked 32nd in the NFL in 2013.) After 8 games, we ranked 8th. Three games later, we've now slipped to 18th.
