Mark Cuban says Doug Christie is “one of those ‘my-body-is-my-temple’ guys.’ And Cuban says it reverently. Christie, 35, takes care of himself in unusual ways, of course, including enveloping himself in the love of his notable wife, Jackie. (And yes, Mavs fans, while the organization isn’t going to bend any rules for her, it has already arranged ways to be sensitive to her needs. If Doug needs guidance from the PR department, for instance, the guidance will come from a male staffer.) In addition to Christie’s defensive mindset, his leadership abilities and his point guard skills, he’s appealing to the Mavs because of the something-to-prove factor: Only the first year of Christie’s multi-year contract is guaranteed. He’ll spent the entire season trying to prove something to everyone, the entire season on a contract run of sorts.
