Mark Cubans a great deal maker but the thing about him is he could buy and sell everyone else on the panel without breaking a sweat. Also the amount most of the people are looking for on the show he could wipe his ass with and not give a fuck. Which is a way isn't good for them because he could very well be fucking around and not care whether they succeed and work to make them so. Whereas if Kevin O'Leary gets his greedy little paws in your business for a big stake I feel like he's going to at least work hard then to somehow make himself a lot of money and vicariously you.
