Warriors general manager Bob Myers is prone to what he calls "work benders," stretches of days — sometimes even weeks — when sleep is minimal. And no period of the league calendar is more chaotic for Myers than free agency. With the negotiating window set to open at 9 p.m. Saturday, he doesn't expect to get a day off until he rounds out Golden State's roster. "That could be end of July, or it could be beginning of August," Myers said recently. "We'll see." In the meantime, Myers will sacrifice sleep to work through a lengthy to-do list.
