Agree LIV is a different model.
Its weakness isnt diference in itself.
But firstly, that it is a poor model. Limited field, closed-ish shop, teams fakeness, and LOUDNESS, That is not a winning formula, or solving any issues the golf watching public has with the existing tours.
And secondly, unlike IPL for example, an established platform for the worlds best golfers already exist. There wasnt a void to fill. Only opposition to poach from. Had they signed the worlds top 50, it would have had a chance. But for a variety of reasons it has singularly failed to attract a critical mass of the worlds top golfer to make limited field work. Money does not seem to have done the trick there.
Between the two, lies its failure, at least in achieving its original goal. It can still have a role as a pre-champions tour, touring the world, with most of its field past their prime. There is a limited audience for that.
