I'm not sure that training is going to make the some of the time into more of the time. Well, not necessarily training in terms of volume of repetitive skill execution.
Brendon Todd leads the PGA tour in fairways hit at >73%. Do you reckon he hits more practice golf balls that Phil Mickelson? In fact, over their careers to date, I'm betting Phil has hit 50 x more shots than Brendon. Who brought home the bacon last week? The left-handed bloke with <50% fairway accuracy. He's confident enough that the rest of his game is more than adequate to be the best that he can deal with more misses than hits of the tee. Doesn't mean he doesn't practice at all but he's not so focussed on it that it he loses focus on the main game, which I think all this Fyfe talk is in danger of doing.
I do think that training, and probably more mental than physical, on composing yourself and having a straight shot rather than defaulting to a panic-looking Gaelic footy snap from 25 straight in front would have a better impact. Is this confidence training or skill training or inseparably both? Bit of a nuance really.
That stupid composite round ball international rules charade has plenty to answer for.
