The idea of banning tees is just another nonsensical wag the dog solution like banning U grooves was a few years ago (although banning U grooves actually happened, where I would put the odds at tees getting banned at roughly 776,542:1).
Why do I say it wouldn't work?
Because a year ago I switched to a Taylormade Original One driver. It has a 275cc head and, at least in my hands, is the longest driver I've ever played. And it's a breeze to hit off the deck. I'm a 10 handicap, so I definitely don't hit it on the button every time. The sweet spot is still a little higher than would be ideal when hitting from fairway. But even if I launch it low from the deck, I still get a ton of run. And if I get the sweet spot on the ball, it goes virtually as far as from a tee. Not to mention, I really love that when I hit it from the fairway I can confidently count on taking the left side out of play... it just doesn't hook away from me like it can when I tee it up.
So what do you think a pro who hits their 3 wood 310 yards would do with a driver engineered to be hit from turf and fitted to their swing and that's harder to lose to a hook? All those guys need is a dime-sized sweet spot anyways. And meanwhile, teeless amateurs will riot and we'll all be standing in shovel holes carved by 25 handicaps who still swing just as hard as they ever did, and make flush contact just as infrequently as they ever did too.
We're going to get pros back to hitting 250 yard drives by banning tees? They're hitting their damn 3 irons that far currently. Didn't Bryson hit like a 240 yard 8 iron on Sunday from the rough? Wait til the scratch players at every club start demanding the tee boxes be maintained at intermediate rough height so they can hit fliers all day.
Want to actually rein in distance? Either rein in the specs, or make accuracy count again.
