Chris Copeland, a training-camp long shot who spent part of the season lugging around a pink knapsack as part of rookie hazing, may turn into a very attractive piece on the free-agent market.

Knicks general manager Glen Grunwald likely hopes Copeland will be part of the team’s future plans, especially after coach Mike Woodson finally turned to him in the crunch of a do-or-die Game 5 and he delivered 13 points and four rebounds in his 19 unexpected minutes in the Knicks’ 85-75 win over the Pacers Thursday night at the Garden.

Of all the summer additions, Copeland became the biggest revelation — even if Woodson refused to use him in the playoffs until Game 4 of the Eastern Conference semifinals.

Considering his numbers, versatility and a changing league bent on 3-pointers, Copeland may seek Steve Novak money, according to a person familiar with the situation. Novak landed a four-year, $16 million package last summer. Copeland has become a more versatile scorer — a 3-point specialist who can put the ball on the floor and score in the post.

Novak got the big number from the Knicks because, through an appeal with the Player’s Association, they were awarded Novak’s early Bird rights.
