Is it possible that working harder on your 200-225 game is more valuable than working on your putting? If so, why is it that virtually every winner is among the leaders that week in putting?
So the thing with that is most players have a baseline range of scores that they shoot. For most tour pros it's probably in the 65-72 range. For the most part, where they fall in that range is dependent on how many putts they happen to hole. But putting is a bit of a crap shoot. Tour pros hole about 15-20% of putts from 20 feet. The nature of statistics is that some tournaments that will be 10% and others 30%. The tournaments where it's 30% are the ones where they have high strokes gained putting and not surprisingly the ones where they are at the top of the leaderboard. The weeks where it's 10% are the weeks they miss the cut.
I think what happens is that in a given round, the range of strokes gained putting could go from -2 to +5 for a given player. But the averages across a season range from about -1 to +1. Sometimes people hole a lot of putts, but no one can do that every week.
Conversely, strokes gained approach across a season ranges from about -2.5 to +2.5. A far higher range, which is why that has more impact than putting. But a given player who has a good approach game probably ranges from +1 to +2, while a bad player might range from -1 to -2. I'm making these numbers up, but the point is that week to week people's strokes gained approach doesn't change very much, while their putting number fluctuates a lot more.
What that means is that someone like Tiger in his pomp could have a bad week putting and his strokes gained tee to green puts him in the mix. When he has a good week putting, the rest of the field look like they weren't even there that week. An average player tee to green is giving up 10 shots on Tiger in a week tee to green. That's an awful lot of putts you have to make up.
The issue I think with Broadie's stuff is that he gives you part of the analysis. If you are a mid handicap say and you look at the difference between you and Dustin Johnson. It likely breaks down something like this:
Off the tee: -6
Approach: -9
Short game: -4
Putting: -4
Clearly there is a bigger difference in the long game. So that might imply you should work on your long game. What I don't think Broadie's stuff shows you is how much work might be involved in improving those. What I mean there is it might be that if you spent 15 minutes a day in your basement working on your putting from 6-8 feet for a week before a tournament, you could make the putting number -2 instead of -4, so you could pick up 2 shots right there. To gain two shots with your long game might need months of work to be done.
Where Broadie's stuff is useful is with a 15 year old kid who wants to go pro. That kid has the opportunity to really work on his game and make real improvements. For him it is useful to know that long game is where it's at.
