Brees completed 18 of 23 passes for 371 yards with five touchdowns and a perfect 158.3 passer rating in New Orleans' 38-17 triumph over the Patriots Monday night at the Superdome.
"They're obviously hitting on all cylinders," said Light. "Drew does what Drew does. I was able to witness that for a number of years. He's got that offense running really well and they were definitely able to make a lot of plays. We got handled in every aspect and we've got to do better."
Light, who returned to game action for the first time since injuring his knee in a Week 5 loss at Denver, admitted it was nice to get back on the field, but it wasn't much of a silver lining considering the lopsided loss.
Light was on the field for both of Laurence Maroney's touchdowns runs -- the only two times the Patriots found the end zone.
"We didn't execute when we needed to execute on offense," said Light. "[The Saints] went out and kept putting points on the board. They put a lot of pressure on us to get out there and make plays and we obviously came up short."
Light said the secret to turning things around was simple.
"Hard work, man. Guys go out there and do more," said Light. "As a team, we have to put a better outing out there in a hurry. I'm confident we have guys that can do that, so we'll get after it."
