Jones is the man to blood England young guns - Borthwick
Eddie Jones is a "fantastic judge" of when to blood Test match novices and will let Elliot Daly loose at exactly the right time, according to Steve Borthwick.
Wasps centre Daly could make his long-awaited England debut in Saturday's RBS Six Nations clash with Ireland at Twickenham, the 23-year-old poised to offer cover from the replacements' bench.
Jones downplayed Daly's status as "a very good player with potential" in the aftermath of England's 40-9 victory over Italy on February 14, but has since drafted in the versatile midfielder after Ollie Devoto suffered concussion.
Assistant coach Borthwick worked under Jones with Japan during the autumn's World Cup, and believes England's new boss has adopted the right strategy by holding Daly back so far during this Six Nations tournament.
"I think Eddie, with more than 20 years' coaching experience at the top level, he'll have seen young players come through and he's a fantastic judge of when is the right time to start introducing them," said Borthwick.
"We want our young players to come in, perform and have long, successful careers with England."
Daly's pedigree has seen him glide through England's age-group ranks before impressing consistently with Wasps in the last few seasons.
The goal-kicking flyer can operate at centre, wing or full-back, and should offer England a host of options off the bench against Ireland on Saturday.
Former England captain Borthwick admitted he had been impressed with the Wasps star's tenacity in training.
"Firstly Elliot's been playing well, I think he's come into this environment, and the times he's been in he's incredibly competitive," said Borthwick.
"He wants to win, wants to do exceptionally well and he trains really hard.
"His versatility in terms of positions helps, his left foot helps, a left-foot kicker is always a bonus.
"He's a guy who is young, got a lot to work on but has come in with a fantastic attitude to try to improve.
"Well I think that for all those players it's an ongoing assessment and an ongoing development process."
