He won't have time to play much golf over these next few months or, if all goes right, years. He's completely driven only to be the best football coach and is prepared to do whatever it takes to win.
That's no guarantee that he will, of course. But he will be getting up early, staying late, doing all the things coaches in the NFL do to keep up with each other in a vicious cycle that passed the ridiculous stage some 30 years ago, when Dick Vermeil took a break that wound up lasting 15 years before he regained the energy to come back.
Kelly is cut out exactly for the job, and there is no doubt he was owner Jeffrey Lurie's first choice when you go back and listen to Lurie's mission statement when starting the job search on New Year's Eve.
"I'm looking for someone that's innovative, somebody that is not afraid to take risks, somebody that looks [at] and studies the league and studies the college world and decides what the best inefficiencies are on offense and defense and special teams and can execute it with their coaches so that you take advantage of trends and take advantage of, again, inefficiencies in terms of where the game is at and understand where it's going," Lurie said.
"So a student of the game who is obsessed and who absolutely and, on his own, is completely driven to be the best, that's what you're looking for."
Lurie might has well have panted Chip Kelly's name, because of the multitudes of candidates the Eagles interviewed for this job that opened up when they decided Andy Reid couldn't do it anymore, nobody fits that description more than Kelly, whose middle names should be "Innovative" and "Risk."
He earned a reputation for being gutsy at the University of Oregon because of his propensity to attempt fourth-down conversions, gadget plays and two-point conversions.
His fast-break offense, which averaged 49.6 points per game in 2012, has been copied by coaches at all levels, including the NFL, a league he won't get his first taste of until Thursday's overflow, introductory press conference, which will include more reporters than the population of Oregon. All trying to ask a question at the same time.
This is where it gets a little tricky.
Despite his qualifications as an offensive innovator and his unquestioned ability to lead, which he proved time and again in his four years as head coach at Oregon, he has never spent one minute in the NFL.
This means he's never been limited by practice times and so many rules regarding pads and contact; he's never drafted a college player; never run a pro training camp; never dealt with an athlete's agent, never had anyone overrule him on personnel; never had to absorb the amount of losses he will have to deal with, no matter how successful he turns out to be with the Eagles.
Kelly lost just seven games in four seasons as head coach at Oregon. He'll be lucky not to exceed that total in his first season here.
Credibility with the players, who all seem to be behind him now, also will erode exponentially quicker than with someone like, say Reid, the minute they sense his system or something he presents to them might not work.
Lurie, general manager Howie Roseman and team president Don Smolenski are no doubt overjoyed with their good fortune to land the person who was at the top of their list from the start. But in the process, they have placed themselves right out on the slippery slope along with him.
There's always less margin for error for a guy who's never spent a minute as a player or coach in the NFL.
Hiring somebody to jump into an NFL head-coaching job with no previous pro experience, at least as a player, is just not done anymore. The last time anyone had any success going that route was the Dallas Cowboys with Jimmy Johnson in 1989.
And if not for the heist of the century he and Jerry Jones pulled off to trade Herschel Walker for five players and six draft picks who turned into the building blocks of three Super Bowl championship teams, the Cowboys never would have won one under Johnson or Barry Switzer or anyone else since that time.
Those kinds of deals aren't available anymore, thanks to the Minnesota Vikings.
So the Eagles are taking an enormous risk in hiring a college coach who takes enormous risks.
Furthermore, what kind of assistants will Kelly be able to surround himself with as he attempts to completely rebuild an experienced staff the Eagles should perhaps have not allowed to defect to Reid in Kansas City so easily?
Will pro coaches want to work under a guy who hasn't paid his dues?
For better or worse, Chip Kelly is the new Eagles coach. There's no backing out now.
A tremendous leap of faith will either be richly rewarded or turn the Lurie/Roseman era into a disgrace.
There will be no middle ground.
