Carmelo Anthony leaped into the second row trying to save a ball he'd batted away, the signature play in another sturdy defensive effort. On the other end, extra passes led to more wide-open shots and the Knicks made it look as easy as they did two nights earlier against the defending NBA champions. Add it up, and New York is perfect after two games for the first time in 13 years. Anthony scored 27 points, J.R. Smith had 20 and the Knicks beat the Philadelphia 76ers 100-84 on Sunday in the opener of home-and-home series.
