Don't kid yourself on how much money chuck is making. He's fighting a couple of times EACH year. How many boxers do that? Chuck will fight 3x this year New years, may 26th and some fight by the end of the year. His take home will be nice. He also gets a lot of endorsement deals, has his training center and everything else. I would easily put his gross revenue per year against any of the top boxers this year.
Call him whatever you want, he's laughing all the way to the bank.
