I understand that these are for pros and would not require the thousands of courses with tens of thousands of baskets to be retrofitted or anything like that. I just enjoy being vocal about things that I think will make the viewing better - I stream almost all the live tourneys that get aired, I love watching.
There's something to using standard equipment from the kids to the pros. 5 year old hockey players shoot at a 4x6 net just like the pros. The basketball hoop is the same size for all ages from the neighborhood to the pros. The height is adjusted for kids due to strength ability - like red or even green tees for the kids - but the goal is the same size.
I imagine it's pretty easy to test the triple bar putting theory. Get some of these pros together secretly in a gym and set up a basket and have them play HORSE and get a film crew. I think I can imagine what it'll look like. Actually I think it would be more fun to putt on one of these baskets than to watch. In the first person view, or maybe as a player standing there close, you can see what the putt needs to do.
On film, you might just see a bending putt come in, and sometimes bounce in, sometimes bounce out. When it bounces out I would think, "good putt, bad luck." Also, due to the design, I think it just moves the target area sideways a bit - If I had a bar in the middle, I'd aim to chain out wide right, and use the right bar to deflect it inwards to avoid the middle bar.
As I'm typing this I just watched the Eagle's place kicker doink a 50 yarder off the goal post - knowing this year they made the posts thinner by a little over 2 feet on each side. I can't say because I didn't play football so I never played on either standard size, but tweaks like this are done for a purpose, I understand. The goal of the goal post change was to create more misses. If the goal of putting is not more misses, but more interesting putts - either you add elements directly on the basket, or elements just outside of them.
I would prefer maybe 2" posts that are placed maybe 12"-24" away from the basket. These would provide the blocking element to force hyzer putts, while not providing a more direct bounce-in effect. The posts could be varying heights - some that are full basket height, some that are only 2/3 of chain height to allow high putts to drop over. They can also be placed strategically to give a better and worse landing area for putts to come in.
I probably like this option because it's mimicking small trees, instead of directly changing the basket design, but to me, the posts option maintains the essence of the game while temporarily at the designer's discretion adds difficulty and strategy to the green. Also, if the posts are painted a certain color, or are bright shiny sliver, it would be picked up better on camera than a thinner bar on the basket.
