Former Australia captain Phil Kearns critical of Eddie Jones coaching methods
Former Australia captain Phil Kearns predicts "fanatical" Eddie Jones will provide England with only short-term success.
Jones has masterminded a first Grand Slam in 13 years in his first season as head coach and is leading the Red Rose in their quest for a maiden series victory against the Wallabies.
Double World Cup winner Kearns, however, believes his methods eventually stop working.
When asked if Jones will make or break England, Kearns told Fox Sports: "I think he will do both.
"I think in the short term they will be incredibly successful over the next two to three years. The big question is what happens after that?
"He is a very astute coach but there is a point where the fanatical work ethic goes too far.
"There's not a lot of people in the world of Eddie Jones. There's one bloke and that's him. That's his world.
"I actually think he is a good guy. But he is massively intense, massively hard working and he ensures his team works hard to the point - I have heard - of overtraining them and really pushing them to the limit.
"I've heard a couple of the guys in the Japan team say they would never play under him again because they could not keep up with the workload it was so intense.
"It will be interesting to see how over time the Pommies go."
