"Unfortunately, nothing will change until slow play starts to affect pocketbooks, sponsors or TV contracts."
/Peter Kostis has the solution to PGA Tour slow play:
Each day before the tournament starts, officials should set the "time par" for the day based on conditions. For example, the officials determine "time par" for the day and announce that the final group of threesomes has to finish in 4 hours and 30 minutes. Then, for every 15 minutes over time par that that group finishes, the tournament donates 10 percent of the purse to charity. If the last group is 30 minutes late, that means the pros will play for 20 percent less money. I guarantee that slow play would stop overnight.
I like weaving in the charitable giving component. Anything to get them under five hours.
Unfortunately, Peter doesn't mention the distance increases of recent as part of the problem with larger fields forced to wait on holes where players can now drive par-4 greens or the entire field can reach a par-5 in two.
Finally, too many Tour events are like I-95 at rush hour. The speed limit means nothing because there are too many cars on the road. Trying to get 144 or 156 golfers around is why we're having so much trouble finishing Thursdays and Fridays on time, and as soon as you have any weather problems, you're looking at a possible Monday finish.
Being the student of history that he is, Peter surely must know the LA Open used to play 144 player fields in the first week of January and finish rounds when days were an hours shorter than in Feburary when they can't finish, even in perfect weather!
