METAIRIE, La. -- A weekly look at what the New Orleans Saints must fix:

The Saints have had a handful of costly errors from every unit during their 0-2 start. The one common bond: They have to be smarter in their home debut Sunday against the Minnesota Vikings.

Sean Payton said his biggest disappointment has been the struggles in "situational football," whether it be the blown coverage at the end of Sunday's 26-24 loss to the Cleveland Browns, the missed blocking assignment on a sack or an offsides penalty on a field-goal attempt.

"That's the one thing that's stood out now, two weeks in a row," Payton said.

The most maddening yet was the blown coverage in the final seconds, when Cleveland receiver Andrew Hawkins broke wide open out of a bunch formation. Cornerbacks Corey White and Keenan Lewis both covered the same player, while Patrick Robinson was flagged for holding another receiver across the field.

“You gotta be able to handle bunch. You gotta be able to handle receiver motion,” Payton said. “I mean, shoot, when you play man-to-man like we do, you’re gonna get that.”

Saints safety Kenny Vaccaro agreed, saying, “We’ve got smart players. It’s just disappointing that we're not playing up to our abilities. I put that on us.”
