Halftime report: Saints 21, Panthers 6

NEW ORLEANS -- A look at four key issues in the first half between the Carolina Panthers and New Orleans Saints at the Superdome:

Missed opportunities: The Panthers had two opportunities in the red zone in the first quarter and got only two field goals out of it. The second was especially costly as they had first-and-goal from the 10 with a 3-0 lead and a chance to take control.

Can't cover Colston: Saints wide receiver Marques Colston found himself open in the middle of the Carolina secondary for touchdown receptions of 6 and 15 yards. He had five catches for 74 yards.

Pass the Tums: Panthers coach Ron Rivera said he kept a bottle of Tums next to him when Saints running back Darren Sproles was on the field. Here's why: Sproles had one rush for 38 yards to set up a touchdown and had two catches for 21 yard, including a 20-yarder to help set up another.

No pressure: Carolina's front four gave quarterback Drew Brees way too much time and he picked the secondary apart, completing 17 of 21 passes for 183 yards and three touchdowns. It all added up to a 21-6 halftime lead.
