Let me preface this by saying that I think Cuban would be a great choice. However, defending his ability to run a business really doesn't do much to further his cause to non-believers, especially in the Cubs case. The man is going to make an obscene amount of money with the Cubs no matter what he does; the question is, is he going to run his business like Jeffrey Loria or like Steinbrenner? And by like Jeffrey Loria, I would mean keep the payroll the same and not drastically change the team. Loria makes a ton of money by selling his young players high at the cost of the team's (continued) success. My finance major friend says he's the best owner in baseball because of his business savvy. I think he's an a-hole. There could be any number of different ways to define the best owner in baseball, and profitability is certainly one. Most fans would use some variation of wins and losses/playoff appearances/world series titles as the yardstick. The Marlins don't measure up too well on that scale, even after having won the WS in each of their two playoff seasons. Regardless, it's pretty hard to make a case for a guy being the best owner in baseball when his team is perennially at or near the bottom of the league in attendance (MLB ranks since 2001: 29th, 29th, 28th, 26th, 28th, 30th, 30th, 30th so far in '08).
