"I don't think there are going to be any apprehensions,'' he said. "I think there are always butterflies on a job for anybody ... it kind of lets you know you're alive and lets you focus on your job.
"But Tony La Russa told me the day you stop getting butterflies is the day you're probably not cut out to do this. You should feel responsibility; you should feel a deep care. ... There's some genuine excitement.'"
Several position players had already arrived in Peoria to get a jump on Spring Training, including new outfielder Jon Jay and outfielder Matt Kemp.
The rest of the position players aren't scheduled to report to Arizona until Feb. 23, with the first full-squad workout set for the following day.
As Kemp looked around the clubhouse on Thursday, he saw several familiar faces and many new ones. Of the 59 players who will eventually be in camp, 41 have three or fewer years of Major League service time.
"Those guys are irreplaceable, but we've got guys here who are capable of doing the job. There's going to be a lot of competition here in Spring Training," he said. "Hopefully, guys are up for the challenge and are ready to come in and work."
Jay, acquired from the Cardinals, could end up in center field or left field. There's free-agent addition Alexei Ramirez, who will be counted on to be the everyday shortstop. There's a host of young arms trying to win jobs in the bullpen, and the back end of the rotation is up for grabs.
In other words, it could be a very interesting six weeks in Arizona for the Padres.
In terms of whether the Padres are rebuilding or not, Green would only say the focus is on getting better each day. He'll let everyone else sort out what the Padres are -- or aren't.
"I think the vibe with everybody as I've gone around talking in the offseason is, we enter the season with no other thought but going out and competing and getting better every single day. If we can improve every day, there's enough people in this clubhouse who have done enough in this game that we'll be right in the thick of it," Green said.
"We'll engage in the work and get better every single day. I tell you, these guys don't lack in confidence, they don't lack for a desire to go prove themselves. It's a different label this year than what the Padres had last year. I think these guys kind of relish that role, and we're going to embrace it."
