Fresh off his Sixth Man Award, J.R. Smith is almost certain to opt out of his contract and become a free agent July 1. The Knicks are praying they are not outbid. At Monday’s press conference, Smith evaded a question on his contractual future, saying he will “worry’’ about it when the time comes. However, in a TV appearance later, Smith said he hopes it works out here. “Without a doubt. I’m born in New Jersey, born and raised,” Smith said. “I would love to retire a Knick.”
