WASHINGTON — The Nets picked up their second win of the season Sunday. Were their victories Pyrrhic, or were they progress? Brooklyn routed Washington 129-106 before a small gathering at CapitalOne Arena, listed as 14,164 but appearing about half that size. They came out on a football Sunday to watch a pair of teams tanking for lottery positioning, and the Nets lose by winning. The blowout saw the Nets improve to 2-11, the third-worst record in the league — and thus, third seed in the lottery.
