"I can't wait, but I'm taking it one day at a time," Foles said after Tuesday's training session. "I'm going to do everything I can today to the best of my ability to prepare for this game, and I'm going to do the same tomorrow."
Chip Kelly made mention of Foles' steady personality on Tuesday, saying it's something he appreciates having in a quarterback. Foles also said he knows how important maintaining a level head is in the heat of a game, and detailed how it's something he has developed over time.
"It's something that's developed through the years," Foles said. "It's important to stay steady. You throw a touchdown pass, it's okay to be excited about it, it's awesome, but right after you're going back, looking at the photos and it's on to the next thing."
His ability to keep his emotions in check helped Foles throw just two interceptions while ending the season with the highest passer rating in the league (119.2).
Foles was comfortable in the Eagles' offense last season because of the way his coaches prepared him for the coming defenses.
"I think the big thing is preparation and what our coaches bring to the table when we prepare for games," Foles explained. "It gives you a really good look so when you get out on the field, you've seen it in practice, you've seen it on film, you know what to do."
This week is no exception to the rule - after four preseason games, Foles and the rest of the Eagles offense have had plenty of tape to review to prepare for the Jaguars' defense.
Jacksonville's defense proved stingy during the preseason, holding opponents to just 16.8 points per game despite losing three of the four games. The Eagles averaged nearly double that during the preseason, racking up 32.8 points per game.
Foles said he and the rest of his teammates have had a good look at what second year head coach Gus Bradley's defense brings to the table, and has been able to identify a few key points in advance of Sunday's matchup.
"It's a very structured defense," Foles said. "They know what they do. They're not going to do a bunch of crazy stuff, but what they do, they do well. They have a great defensive front with a solid secondary that will get you if you try to force a ball. They're held down by (Paul Posluszny) who's a great player who really moves around a lot, so it's going to be a good challenge for us."
With just five days between Foles and the first kickoff of the regular season, the returning starter is continuing to approach this week just like he approaches everything else - level headed, and one day at a time.
"We come here, we have practice, we have meetings, and on Sunday I'll be ready to go," Foles said. "But until then it's a work week, one day at a time, just trying to get everything in place."
