The Knicks are “unhappy’’ about a change in the terms of the Rockets’ offer sheet for Jeremy Lin, according to an NBA source, after the offer was bumped to $25 million guaranteed over three years,

Despite their anger, the Knicks still are expected to match it in the next three days. That doesn’t mean they are thrilled with their point-guard prodigy, who has a resume of 26 games with starter’s minutes. As of last night, the Knicks had not received the offer sheet in their hands as the Rockets continued to play games.

Knicks coach Mike Woodson, who gushed three days ago about Lin keeping his starting job when training camp opened, seemed cooler Friday.
