1The tight ends and running backsThey are giving the Cowboys fits in coverage. The San Diego Chargers and Denver Broncos in the past two weeks showed patience against the Cowboys’ zone coverage, dinking and dunking on the way to big plays. The Washington Redskins don’t have the same quality of tight ends, but they do have quantity.2Keeping it wide openThe Cowboys might have hit on something — throw it deep and throw it a lot — in their loss to Denver last week. Coach Jason Garrett and owner Jerry Jones both tempered expectations for that blueprint the rest of the way, saying each game is different. But it sure proved intriguing.3Return of the sackSince starting the season with 13 sacks in three games, the Cowboys have recorded only one. They couldn’t get to Peyton Manning at all last week, and they got to Philip Rivers just once. Coincidence that they are two of the quickest ball-releasing quarterbacks in the NFL? Probably not.4Safety contributionsSince becoming a starter three games ago, J.J. Wilcox has made 15 tackles, but he has no interceptions or pass breakups. He had one pick wiped out by a penalty. Coach Jason Garrett said the Cowboys are not lacking big plays from the safeties.5TurnoversAlfred Morris was a nemesis against the Cowboys last year, but he has a weakness the Cowboys want to exploit. He’s fumbled five times in his short career, losing four. He fumbled on his first carry of the year. The Cowboys have 10 takeaways in five games.
