Just off a baseline inside Guy V. Lewis Development Facility at the University of Houston, Warriors coach Steve Kerr found himself in a familiar place Thursday afternoon. For four of the last five postseasons, Kerr and the rest of the Warriors used the adjoining facilities to train while in town to defend their championship ambitions. On this trip, Kerr -- hours removed from his latest blowout loss to the Rockets -- has a different mission than he's used to: building a championship mindset instead of maintaining one.
