5 Douglas Jardine
To explain my selection, LLoyd lead the greatest Team ever in Test Cricket history in terms of the quality of players and their absolute invincibility against oppositions in variety of conditions (home or away). He was himself a great batsman and occasional bowler and he made it into Test cricket's most successful Team.
He also lead them to 2 World Cup wins in the first 2 World Cups.
Alan Border built an Australian Team after it had been run over by Kerry Packer's World series Cricket and from the ruins he built it over time into a Successful Team from which his succesors have progressed and benefitted from his great stewardship. This would not have been possible or forseeable when AB took over the Team. He also lead Australia to its First World Cup win in 1987.
Arjuna is much maligned for his confrontational nature, but for a country which came into Test Cricket and was struggling through its early years in Test Cricket, Arjuna was a strong leader who moulded it with his strong leadership skills and his positive influence on players in his wings. If not for his strong leadership and astute captaincy , the 66-1 outsider would have had no show in winning the World Cup in 1996. His succesors have helped the Team develop further, but have benefitted from the overwhelming contribution by Arjuna to Sri Lankan Cricket.
Steve Waugh as a Captain lead from the front and the numerous occasions he saved his Team and turned around the fortunes of his team are well known.
Douglas Jardine was much maligned for devising the leg side theory after strategising with his leading bowlers Larwood, Voce, Bowes long before the Body line series of 32-33, as to the best way of tackling the then Aussie cricketing juggernaut lead by Sir Don Bradman, who otherwise would have run rampant . You may hate him for this but, it was legal and within the rules of cricket then and he lead his Team from the front. Unfortunately the English cricket establishment then failed to stand by their captain and he ended up being hounded and maligned and leaving cricket as a tarnished individual. A fate undeserved in my opinion.
