Garden of dreams

Link:Rashard Lewis called his winning three-pointer “big-time, especially here in New York City at the Garden.” It was his only MSG appearance of the season, but might he find his way to the Knicks in the summer? The 25-year-old forward, who was the subject of trade speculation before the Feb. 22 deadline, can opt out of his contract after this season. The salary cap-restricted Knicks would have to work out a trade in order to land Lewis, who would forfeit $10.1 million next season and $10.9 million in 2008-09 to become a free agent. The midlevel exception, which maxes out at around $5 million a year, certainly won’t cut it. But it’s likely the Knicks will explore something if Lewis is available.
