If the Dallas Mavericks are anything, they’re consistent. For the past two decades, under the leadership of Mark Cuban, Dallas has spent its waking moments hunting its elusive prize. So determined, the Mavs would chase him round Good Hope, and round the Horn, and round the Norway Maelstrom, and round perdition’s flames, before giving him up. The chase continues today on the seas of free agency as they stalk their tormenter and constant companion. This summer, Dallas will again play the lead in a tragedy of their own creation, tasked and heaped to strike through the mask and claim their prize.
