LOS ANGELES – The Knicks are a Greek tragedy. They are Hamlet and MacBeth combined.

Knucklehead Al Harrington cost the Knicks victory in regulation tonight by slapping the backboard and hanging on the rim after a putback dunk. The technical foul allowed the Clippers to rally from 3 points down in the final 25 seconds to steal the game before a whole slew of Knick fans inside Staples Center.

Eric Gordon, whom the Knicks should have taken at 6, burns them for 30 points, with two big plays in overtime while Danilo Gallinari continues to regress, all done in front of Donnie Walsh and James Dolan. Zach Randolph ties the game to send it to overtime with a big inside hoop the Knicks never get in the clutch. And did I mention Fred Jones, whom the Knicks never considered re-signing, came off the bench with two big baskets down the stretch.

A six-game losing streak. A season-worst 10 games under .500. A Chris Duhon ankle sprain that could turn out worse. A knucklehead forward whose considered their go-to scorer. A roster that has more dead spots than the old Boston Garden’s parquet.

At the All-Star Break, the Knicks are in the playoff race on paper only.

It’s onto Phoenix for All-Star festivities, to first cover Nate Robinson and his “KryptoNate” dunk. D’Antoni admitted it was a good time to get away from each other. Indeed, D’Antoni looked like he wanted to take Al and shoot him outside the bus.
