Andrew Strauss called for England's bowlers to step up after the omission of James Anderson and Stuart Broad against the West Indies but suggested the pair could feature later in the year.
England's interim managing director Strauss, interim coach Paul Collingwood and head scout James Taylor made up the three-man selection panel for the series, which starts in Antigua on March 8, and opted for a host of changes to the side.
Joe Root will once again lead his country, despite a 4-0 Ashes hammering by Australia in December and January, with Collingwood acting as interim coach following the departure of Chris Silverwood.
Anderson and Broad, who have managed 1,177 wickets in 321 Tests between them, were the most notable names left out of the touring party for the three-Test series in the Caribbean.
Lancashire pair Saqib Mahmood and Matthew Parkinson, along with Yorkshire's Matthew Fisher, were all included as the trio eye red-ball international debuts.
Strauss challenged the bowlers of the new-look squad to deliver in the absence of their evergreen stars, insisting that both the fresh faces and the more experienced players – such as Chris Woakes, Mark Wood and Ben Stokes – must step up.
"This is an opportunity to refresh and look forward," Strauss told BBC Sport in an interview published on Wednesday. "We've brought some new blood into the bowling resources.
"But we're also asking some of our existing bowlers to play a slightly different role to the one they've played before and show a bit more leadership."
Strauss reiterated the omission of Broad and Anderson does not signal the end for the duo, while he denied the pair's stature could be intimidating to captain Root and his younger players.
"They've earned the right to have that stature," he added.
"But we also have to think that there is life beyond them as well and we need to develop some of the other bowlers and allow them to play more of a leadership role, rather than just a followership role.
"No-one is saying Broad and Anderson won't feature this summer and beyond.
"My job is to give the new director of cricket and coach options from which to pick and we can learn more about the options we do have on this tour.
"The new coach and director of cricket will look at selection for the summer and Broad and Anderson will be very much in the mix."
Former opener Strauss also confirmed that Root will come in at number three, while the uncapped Durham batter Alex Lees will partner Zak Crawley at the top of the order amid England's ongoing battle problems.
"A lot of our batting problems have come at the top of the order," Strauss continued.
"Alex Lees comes in as a mature cricketer who knows his game well and it's an opportunity for him to stake his claim with Zak Crawley.
"Joe Root has said very categorically that he wants to bat at three and take that responsibility on.
"That's quite a fundamental shift in itself and creates a bit of space in the middle order for some of the less experienced players to play better and more consistently."
