I don't neccesarily agree or disagree but do you have any evidence to suggest that Sinclair is not popular?
More often than not rumors about team dynamics are true. Hence that's how rumors start. When Jesse Ryder came into the team, without really knowing him as a player, we already knew him as the dodgy alcoholic.
It's quite easy to spot the team dynamic whenever they field. When they crack a joke with one another, etc... when it's time to get serious, when it's time for a break. You can even try and see when they are off it, when the camera pans to the players how they react to one another.
I've seen Sinclair play in the national team since his 200 on debut. Granted, I was more a rugby mania than cricket fanatic then, but you'd still notice news articles when he's first dropped from the team, etc. Over time, you'd realize that he doesn't fit into that national team setup. It's such a shame.
I don't want to stir up another one, but Fleming's strong personality also doesn't endear himself to his teammates often either. Often he is seen as a clinical, somewhat cold leader to his team. But that is a non-issue, because without that strong personality, he won't have become captain at 23. And a fine captain he is too. He's mellowed out a lot as he wound down his career, maybe that's why he didn't take the captaincy drop too hard.
Another one, is Braces. He is the reason why the team's xp points dropped thanks to his personality, his way of communicating with his players, and a lot of players not understanding his reasons.
Styris retired because he doesn't get why he got dropped, Fleming is bemused by his loss of captaincy in tests, McMillan finally got dropped for once, and when Braces first got the job, all the experts reckoned Fleming and Braces would clash. And rumors are they have "disagreed" a lot behind closed doors. Fleming wanted to run a corporation of his own cricket team, and Braces wanted more control than Fleming is willing to concede.
Look at Fleming's career path after cricket. To be a leader consultant in a firm he started up and he'd rather do that than to keep 'leading' the current cricket team. I hope one day this is revealed as transparent as Astle's book about Braces' "management" skills. Astle didn't like the "team critique session" hence why he retired prematurely too. Cairns left the team way too early because of the same reason. That stupid high performance Aussie (forgot his name) put in a system to place the senior players under pressure and worry about their spot on the team. This is a high talking point in the news too some time ago, and it's the reason why our senior players retire WAY WAY too early. Look at how old the Indian cricket team are.
Cairns, Astle, Styris, McMillan all had at least another 5-6 seasons in them.
Oh about Lou Vincent, he;s another casualty from this current coaching setup.
COnsequently, that same Aussie high perfomance manager went to India, 'managed' to turn their national Hockey team from world beaters into a team that didn't qualify for world champs. What a joke he is.
