Essex head coach Paul Grayson is planning to give some of the club's promising young players a chance to impress in 2015.
The county begin their Division Two County Championship season against Kent at Chelmsford on Sunday, 19 April.
"There'll be a big emphasis on giving opportunities to some of the younger boys," Grayson told BBC Essex.
"We let four or five go, but we've recruited younger lads that have come through the system."
He continued: "I've every confidence the likes of Callum Taylor, Tom Moore and Jamie Porter will bowl very well for us.
"We'd be fools to try to integrate six or seven of the younger lads at the same time, but we're trying to bed in one or two. The squad looks good and everyone looks really fit."
Grayson said the club would cope with the departure of players including left-arm pace prospect Tymal Mills, who signed to play first-division cricket for Sussex.
"We'll miss his pace, but Tymal hardly played any cricket for us last season, and given some of the Division Two surfaces we played on last season, I've every confidence Jamie Porter and Callum Taylor will bowl very well for us in those conditions," he said.
"Obviously we have Shaun Tait arriving for the T20, and [overseas player] Jesse Ryder gets here on 10 April, so he will have a good week's preparation for the first game against Kent.
"I spoke to Jesse a couple of nights ago and he's really looking forward to coming back and seeing the boys again."
Grayson confirmed England Test captain Alastair Cook has resumed training with the county, though Essex are not anticipating the left-handed opener being available other than for the occasional one-day game.
England one-day international Ravi Bopara will also be missing for a large part of the season, having signed to play in the Indian Premier League.
