Okay, I'll bite back, Global.
Starting a sentence with "But" is not a grammatical error. Common construction in modern journalism
Two buts in a sentence is awkward, agreed, but how anal do we want to be? Would you really hang a sub-editor for it? You could find a similar construction in any daily newspaper
His use of the phrase "effect a turnaround" is actually correct. Honest. (You are giving "effect" to the concept of a turnaround, rather than seeking to affect it.)
"Ever" is an unfortunate typo, agreed.
If a journo wants to use indefatigable, so what? It's not exactly ante-diluvian. The word "hairs" and "splitting" come to mind.
Tony is putting forward his thoughts as part of his remit as a sports writer. Naturally others will see it differently, but that doesn't alter his brief to set out his own views.
Some - like you - will criticise him for being too positive given Canterbury's poor performance.
At the same time others will criticise him for being too negative (check out the other moans on this forum from fans who hate it when a journo criticises anything)
As a football fan I would tend to agree more with some of your counter-ideas, as it happens.
But there is no suggestion Tony has a monopoly on truth. (sorry about that "but" usage, by the way, I can see you hate it). At best a sports writer should agitate, invite ferment and challenge ideas.
Tony's put out some ideas in print. You've popped down a few yourself. Nobody is right , nobody is wrong.
Email him with some feedback, I reckon. He'd be just the sort to encourage a dissenting viewpoint.
Hope this helps.
