Heading into this season, the NFC South was widely recognized as the most loaded quarterback division in the NFL, with Matt Ryan, Drew Brees, Cam Newton and Jameis Winston all capable of leading their teams to the playoffs.
That may still be the case. But for any of these teams to make a serious push, they'll need more consistent play from their QBs in the second half. All four have underachieved to one level or another. Brees has arguably played the best so far (he is the only one with a top-10 passer rating this year).
