I believe currently he's an independent contractor in sales, but I think he's referring to past jobs where he's managed small teams and had to deal with budgets.
My personal perspective is that I'm voting for someone with character and vision. Someone who will do what's best for the sport, not just convenient or beneficial for himself. Someone who will make the right decision for the next 10 years, not the next 6 months.
It's the job of the board to advise on particular areas like finances and legal compliance, either from board members who have the personal experience (like A3), or through bringing in advisors (like the Org's attorney of record), and the President's job to take that direction and advice and act on it. None of the candidates have significant non-profit leadership or management experience that I'm aware of, so in that sense it's a wash.
