The key factor to the success of the LIV Tour is what happens to the Majors, in my opinion. If players can play the limited number of LIV events for big money and still play the 4 Majors, that may be all many players want.
But the main factor to the entry to the Majors, in my opinion, is whether the LIV events get counted for World Ranking Points. Sure, the top guys--who have won recent Majors--may get into future ones--at least for a while. But for most of the others, their way into the Majors is through OWGR points. Without these points, the LIV Tour may fail.
In my opinion, these events--with small fields, 54 holes only, etc.--are more like exhibitions and shouldn't be given points. And certainly the politics of the decision to award these points tilt away from the LIV Tour.
We'll see!
