Sacramento Kings fan Bob Dreizler would describe himself as a perpetual optimist. But as he left Sleep Train Arena on Sunday, having just watched the hometown Kings lose another game, he was not feeling particularly optimistic. "Honestly, I'm sort of discouraged," Dreizler, a Sacramento investment adviser, said later by phone. "I feel like this is the season the team had to do well, otherwise the fan base is going to start to shrink. You (can) already see that."
