Quote jsb1990="jsb1990"Appointing etheir Lowes or McDermott would be another step backwards IMO Lowes proved nothing when he was coach at Warrington and McDermott is proving nothing at Harlequins.'"
Being a great player has never meant that you will automatically be a great coach, some are, some aren't; often it's the unsung 'lesser' players who make the better coach, Peter was the least decorated of the Fox brothers, but neither Neil nor Don made it as coaches, whilst he was one of the best of his era.
Leaving that aside, it's far too early to say whether Lowesy or Brian Mac will be successful head coaches. For Brian in particular, you say he "is proving nothing at Quins", though you don't qualify this, but he was highly regarded at Leeds when second in command to Smith and has taken on a difficult role at Quins (a role which in all fairness, I don't think compares to the job at any other club, tbh) and not only that has seen his squad cut to ribbons before the season even started.
I don't think Brian was ever expected to win SL: much of what he has achieved is behind the scenes (a bit like Stevie Mac at the Bulls, in fact), putting systems into place and getting the basics right, and though I guess he'll be pretty disappointed with the way his team has performed on occasions, given what has happened to his team on the injury front, it's difficult to think anyone else would have done much better.
Maybe both Brian and Jimmy would have been better starting in the traditional manner, in the lower divisions? Coaching, in any case, is a job with a wide variety of tasks within it, coaching juniors, intermediates, top-end amateur, professional level and up to head coach in SL and the skills required are many and varied. The best junior coach in the world might not cut the mustard with pros and by the same token the best SL coach might be rubbish with the kids. So which is the best coach?
