That is quite an accusation. Do you have any facts comparing 2019 to previous years (crowd sizes, advertising dollars, etc.) to back it up or are you just repeating "trade show whispering"?
One thing I think alot of people overlook when comparing B.A.S.S. to M.L.F. is exactly what each organization is. MLF is basically a labor union, where those who perform also run the organization. Their number one concern is the well being of the anglers, followed by pleasing the advertisers and with the fans the lowest priority.
BASS is the nations largest fishing club. Members do not own the organization, but can participate in tournaments that the organization puts on. If it held no tournaments, BASS would still exist. Their number one concern is the well being of their members, followed by pleasing the advertisers and then the tournament anglers being the lowest priority.
MLF's format is more attractive to the beginning angler or non anglers. More enthusiastic anglers, ones who would pay to be a member of BASS, find the largest five format to be more interesting. With the sudden departure of well known anglers, there currently is more name recognition at MLF, but how long will that last? Us old folks remember when Larry Nixon & others left BASS to go to FLW, but those under 35 years old would ask "Larry Who?". The organization makes the names and in a few years, anglers like Brandon Cobb and Patrick Walters will be just as well known as Jacob Wheeler and Brandon Palaniuk were when they had their early success.
The one question that I haven't heard asked is what happens when 2 or 3 or 10 anglers leave the BPT in order to re-qualify for the Elites? It is going to happen, not everyone was happy with the inaugural BPT season.
