You can't design a golf ball that Harman can hit as far as Bryson.
I'll argue that the longer ball/driver has leveled the playing field because the driving length has increased more than the length of the holes. 30 years ago, only John Daly could get on a 600 yd hole in two, now there are 30+ players who can; in general, holes can not be lengthened to 700+ yds.
I'm not certain the length issue is actually a problem, or at least one that can be addressed pragmatically. First and foremost, it's really all about the money. If the R&A, the PGA and the USGA all get together to restrict drivers or the ball, several things will happen. Recreational players like me will stop watching and/or attending, correctly sensing there's no longer a connection between the pros and the game we play.
Also, pros get paid a lot of money to use/endorse certain lines of equipment/play certain balls, and if they stop, it will have an impact on the producers' income, and thus the players.
Furthermore, the lawsuits will begin almost immediately, in a theatre that's already plagued by big money interests fighting it out in boardrooms. Again, the playing public will lose interest.
Do you think such a move will not immediately drive dozens of more players to the LIV, rendering the PGA and the DPW tours unto triple-A status while the real stars are now at LIV? Does anyone think Peacock or someone like them won't suddenly jump ship?
And finally, who said the course must be able to defend itself? Where does that idea come from? A bunch of ossified, knee-jerk reactionaries whose playing experience is no longer relevant and are perversely leading the revolt against the future? I never liked Jack Nicklaus in the first place, and still don't care for anything he has to say. It would be pure poetry, a monument to the pursuit of policy contrary to self interest, if he and his ilk led the charge that killed the goose that lays the golden eggs because they resent that the game has passed them by in their decline.
BTW, this is not a shot at you
Oakland, just all IMHO.
