The Sacramento Bee (Scott Howard-Cooper) writes: Don Nelson has the look and sound of someone trying to get fired. This comes as no surprise to those who know him well: thrive in the underdog role, scuttle the ship when people get excited for a genuine payoff. Except that, now, the timing is curious even by his standards. He signed a two-year, $12 million extension in October, set to begin after the current deal expires with $5 million due this season. One of Nellie’s closest friends, Larry Riley, was moved from the bench to the front office to handle personnel matters in place of titular head Chris Mullin. Nelson is entirely in position to be at the intersection of everything that goes on with the Warriors, without having to get bogged down in management minutiae. There is no such thing as shocking in the Nelson world, but quitting and walking away from $12 million would qualify. No one expects that to happen. Moving himself into the line of fire to become the seventh coach to get the ax, that’s another story. He would get a sizable payoff and the freedom to swing a new deal elsewhere, if he suddenly feels tough enough again.
