The New Orleans Saints and Green Bay Packers kick off in merely a few hours, and in Week 2 of the NFL Preseason, New Orleans needs some serious questions answered.

Kickoff is scheduled for 7 p.m. ET at Lambeau Field after a week of joint practices between the two teams. So, ahead of the game, let's take a look at two key questions that need to be answered by the end of Friday night.

1.) How good is the offensive line against pressure? 

In Week 1, the offensive line gave up five sacks. Yes, you read that right.

Rookie Trevor Penning allowed four pressures against Houston. All of his teammates up front combined for five.

All in all, it wasn't a pretty performance from the offensive line. New Orleans needs to see improvement in Week 2, or it might be time to start thinking about upgrades.

A weak offensive line makes it difficult for the coaches to evaluate how well players like Ian Book are playing. Under constant duress, Book hasn't found his footing. With decent offensive line play, he might.

2.) Dark horses at wide receiver

Late in Friday's game, there will most likely be a battle at the wide receiver position. New Orleans' top four is pretty much set, but after that, things could go in a number of directions. Established players like Marquez Callaway and Tre’Quan Smith lead this group. However, Kirk Merritt and Dai’Jean Dixon could make things interesting with their effort.
