The Lakers are learning all about "Lin-sanity," trailing the New York Knicks while second-year point guard Jeremy Lin rips through them.

Lin has 18 points and five assists for the Knicks, who lead at halftime, 49-41, Friday at Madison Square Garden.

The Lakers (15-11) haven't been very solid in any phase of the game, shooting 34% and committing nine turnovers. Kobe Bryant has 10 points on one-for-six shooting.

Andrew Bynum has two points on one-for-five shooting. Derek Fisher and Steve Blake have each missed four of five shots so far.

The Knicks (11-15) are playing without two starters: Carmelo Anthony is sidelined by a strained groin and Amare Stoudemire is away from the team because his brother died earlier this week.
