I don't beliefe it is Golf Digest's intention that 4 1/2" wide cups be abolished in favor of 15" ones. This is not some Dr. Evil plot to take over the world; just a one-day experiment to see what happens and, as John Kavanaugh rightly indicated, sell a few more magazines because of the feedback they will compile into an article about the experiment. I don't get the feeling that Golf Digest is trying to forge some new, supposedly improved game out of golf. TaylorMade's CEO just made a suggestion to Jerry Tarde and he ran with it. I really don't think anyone expects this to be the way of the future.
People can't even get the USGA, the R&A, or the PGA Tour to adopt the tougher-to-use ball that lots of people think is needed to help the game out. What makes anyone think the 15" cup is a threat to infiltrate the game?
This doesn't strike me as much more radical than a one-club tournament, yet people participate in those more often and find them to be interesting and fun.
