How the Mavericks made it from March 11 to the bubble relatively whole is a triumph in itself. The backstory is crazy. The steps were complex and painstaking. Clearly expensive, too, although the man footing the bill insists he hasn’t so much as peeked at the still-climbing tab. “I honestly don’t know,” owner Mark Cuban said. “I have no idea. I told them to do everything the right way, with the guys’ mental and physical health ahead of everything. “I’m truly afraid to look at the Mavs financials, so I haven’t. I know it sounds crazy, but it is true.”
