2.5 million in my opinion is not enough for the feat that this man/machine performed. I feel safe in saying that less than a handful of people, possibly no other person could have or will ever match this record.
Yes 2.5 million is an ungodly amount of cash, but probably 20% of all the uneducated, ill mannered, unappreciative, greedy, professional (I use this term lightly) athletes in the world make that kind of cash yearly.
Just My Opinion of our mis-guided world.
