The performances weren’t consistently poor, but a big play here, too much time in the pocket there, and the inability to get a linebacker in the flat now and then will undermine your talent when those things are happening every game. “We’ve done a great job of eliminating, for the most part, the big chunk plays,” coach Sean Payton said. “And then I just think that, overall, we found a niche.
