PHILADELPHIA — Howie Roseman and Nick Sirianni sat down for their opening news conference about 20 minutes before the Philadelphia Eagles’ first practice. They were quickly peppered with a question about Jalen Carter’s new contract.“No welcome back? No, ‘Hey guys, how’s it going, how was your summer?’,” Roseman said. “We got football back in Philadelphia! It’s a beautiful thing.”Yes, football is back in Philadelphia. The start of a six-month journey (and if they’re lucky, into a seventh month…) began at the team facility on Wednesday morning. The emphasis in Sirianni’s opening team meeting was about “being together and being aligned,” per quarterback Jalen Hurts.“100 percent alignment, zero percent entitlement,” said Hurts, revealing his notes.Here are 10 things we learned and observed on Day 1:1. Jonathan Greenard opened training camp on the physically unable to perform (PUP) list. Greenard, the team’s marquee offseason acquisition, suffered a strained pectoral lifting weights before camp. The team does not expect it to be a long-term absence.“One of the things that we know about Greenard is he’s going to be ready to play,” Roseman said. “Training camp’s so important, practice is so important, but when you have a guy like that who prepares the way he does, who has the experience in the NFL the way he does, you know he’s going to be ready to play when we start the season. We want to be smart with all our guys and get them ready, but at the same time, acknowledge the process that they have to take to make sure that they are 100 percent when they come back. This is not a long-term injury. This is nothing we’re concerned about.”By opening training camp on the PUP list, the Eagles preserve the option for Greenard to open the season on the PUP list if the injury lingers longer than anticipated. Greenard was a spectator at practice.
