This crazy and chaotic Knicks season could be extinguished in the first round of the playoffs tonight.

The blue-and-orange jalopy that is the Knicks barreled into South Beach for the do-or-die Game 5 against the Heat with a one-handed power forward, a starting point guard who was a fourth-stringer in March and a maligned superstar who went from goat to hero Sunday by finding his shot and 41 points.

The Knicks’ starting backcourt that opened the series — Baron Davis and Iman Shumpert — stayed home, disabled with devastating knee injuries. Sore-kneed Jeremy Lin, the team’s most famous player globally and former coach Mike D’Antoni’s starting point guard, made the trip to Miami, but was ruled out for the series yesterday, ending the Linsanity Watch.

On the Knicks’ last visit to AmericanAirlines Arena, paramedics raced into the locker room after Game 2 to tend to Amar’e Stoudemire. Punching a glass-enclosed fire extinguisher outside the locker room in an impulsive fit rendered a massive cut on Stoudemire’s left hand that came a millimeter from severing a nerve.
