Theres always this story of him Funnelling venture capital into fights/fighters... Surely noones still falling for that if its not profitable...
Given whats happening with Kinahan does make you wonder about what money is been funnelled in...
I have No reason to think Haymon is dodgey, but this "venture capital" story has been going too long to be true, people dont just invest to lose, unless the money they put in is shadey, and the money they take out is clean... then they are fine with losing.
