Amar’e Stoudemire’s ceiling was immeasurable when he first entered the NBA and began establishing himself as an elite power forward. But all these years — and knee surgeries — later, Stoudemire’s ceiling, as determined by the Knicks’ medical staff with some input from Mike Woodson, is the same as your standard television sitcom: 30 minutes. Think of Stoudemire now as a “Seinfeld” rerun with a better jump shot but not quite as funny. “That’s fine,” Stoudemire said of the minutes restriction. “I have no problem with it at all.” Stoudemire has been the consummate professional and teammate since returning in January from knee surgery and accepting a significantly reduced role. Despite having started 624 of 641 games in his career before this year, Stoudemire has come off the bench in 23 games this season. He is averaging 22.8 minutes and has gone over 25 minutes only eight times. “Thirty minutes is the max, he knows that,” Woodson said as his team prepared for Wednesday’s game against the Golden State Warriors. “I think a lot of things can be done in 30 minutes. I’m ecstatic. I look at it in the long run his minutes are limited to 30 and if he is talking about extending his career I think it’s a great position to be in.” The Amar’e Rule is a concession to Stoudemire’s knees, which the Knicks knew were damaged when they signed him to a five-year, $100 million contract in the summer of 2010. In fact, Stoudemire has been deemed such a medical risk that his contract is not insured. The Knicks have every reason and right to do all they can to keep Stoudemire healthy and productive during the length of his contract. It also allows Woodson to limit the amount of time Anthony and Stoudemire play together since that combination hasn’t translated into- wins since Anthony was acquired two years ago. Read more:
