METAIRIE - Tracy Porter grew up in southern Louisiana, so he thought he knew what to expect.

Sedrick Ellis tried as hard as he could to prepare himself for it.
But both players found themselves gasping for air when the New Orleans Saints opened their weekend rookie mini-camp Friday.
"It's definitely a little different," said Ellis, a defensive tackle from USC that the Saints selected with the seventh overall pick in the NFL draft. "Even when you workout in California and you think you're in shape in California, you come out here and the air's a little different.
"The first day was a lot more difficult than today was. My body is getting more used to it and we're working it out."
Porter, who prepped at Port Allen High School before heading to Indiana, said he thought he was prepared to return to the region's heat and humidity.
"It's been a while since I trained or practiced here," said Porter, who was selected in the second round. "So for the first periods we had at practice, it's pretty difficult for me. After I adjusted, things just started falling from there."
Conditioning aside, Saints coach Sean Payton said he's been encouraged by the play of the team's 2008 draft class.
"I've been very encouraged from what I've seen from the class in general," Payton said Saturday. "The big guard from Nebraska (Carl Nicks) has done a good job of stepping in there.
"When you look at Ellis, he's been a pain in the rear for a couple of days now splitting some double teams and getting in the backfield.
"Porter showed some of the coverage skills we're anticipating. (Adrian) Arrington, the receiver (from Michigan) we drafted in the seventh round, has done a good job of handling the assignments. I think he's a pretty smart kid. Overall, I've been encouraged."
With Ellis' former defensive coordinator at USC, Ed Orgeron, now coaching the Saints' defensive line, the 6-foot-1, 305-pounder has been able to pick up on the team's scheme pretty easily.
"I think you can always improve," Ellis said. "I'm very happy with how fast I'm catching on to the system. The plays that they've put in and the stunts, I've been able to grasp them pretty quickly.
"You can always get better as a football player, technique-wise. You haven't played football in a while so you want to hone in on your skills this weekend."
Ellis has been working at nose tackle, while fifth-round pick DeMario Pressley (from N.C. State) has been working at the three technique, or the defensive tackle position.
"We initially brought them in at that position because that's what they played in college," Payton said. "Ellis is more familiar in the nose and I think he's got flexibility and we'll want to work him at the three also.
"I think (Pressley's) going to be able to get stronger in our program. I think that will be important for him. He's got athletic ability. His body of work isn't as good as Ellis, but nonetheless, he's a young talent we're excited about."
Payton has also been encouraged with the play of Porter, who's always getting reps in the return game.
"Porter's got good ball skills," Payton said. "When a corner doesn't have good ball skills, eventually there's no downside to throwing in the direction of a corner that can't catch real well. It's either going to be complete or incomplete.
"Now, when a corner does have good ball skills, your location has to be a little bit more exact because he's capable of picking off a bad throw. He gets his hands on a lot of balls. I think he's got a lot of good cover skills."
The rookie mini-camp will conclude today. The Saints will then break camp and return to offseason training, before returning to Metairie on the last weekend in May for mini-camp.
"It's hard to tell (where some of the players are) because we've got such a mixed group," Payton said. "You have to be mindful of who Porter is covering or who Ellis is beating on a double-team or who Nicks is blocking. I think you'll get a better indication of how they're doing when they're with the veteran players."
