A slim and sleek Amar’e Stoudemire raced down the floor looking to establish position with his back to the basket. James White fed him the ball. Stoudemire turned, put a head fake on Earl Barron, and exploded to the rim, using an up-and-under move to convert a basket.

It came during an informal 4-on-4 scrimmage yesterday at the Knicks training facility after the formal practice ended in preparation for Game 3 tomorrow between the Knicks and Pacers in Indianapolis.

Before the scrimmage was over, Stoudemire had tested most of his offensive moves, especially his fade-away jump shot from 12 to 15 feet. If all goes well during his recovery day today, Stoudemire should see his first action of the playoffs tomorrow.

“I expect to play at a high level,” he proclaimed.

A quality 10 to 15 minutes would be welcomed.

If the Knicks can get that out of Stoudemire, it will enhance their chances of advancing past the Pacers and into the Eastern Conference finals. Those who believe Stoudemire’s arrival is akin to mixing oil with water are misguided. Not only can Stoudemire help the Knicks, he deserves the chance to avenge his two previous playoffs sabotaged by injuries that could be viewed as either unlucky or self-inflicted.

Stoudemire needs to have success in this year’s playoff run to make amends for being less than his best the two previous seasons. In 2011, he injured his back attempting a trick dunk during warm-ups before Game 2 of the Knicks-Celtics first-round series at Boston. After scoring 28 points in Game 1, he totaled just four and seven points in each of the next two games as the Knicks were swept in four.

Last year, Stoudemire suffered a deep laceration to his left hand after he hit a glass covering a fire extinguisher while walking toward the locker room following a Game 2 loss at Miami. He missed Game 3 and the Knicks were eliminated in five.
