From ESPN.com:
The New York Knicks traded center Nerlens Noel and guard Alec Burks to the Detroit Pistons — clearing $19 million in additional salary-cap space — and they are now able to make an overwhelming contract offer in the neighborhood of $110 million to free-agent guard Jalen Brunson, sources told ESPN.
The Knicks included two future second-round picks and $6 million to incentivize the trade, sources said, and they now have approximately $30 million in cap space to make a massive four-year offer to Brunson. The offloading of players and assets to create the space clearly reflects the Knicks’ confidence they can reach an agreement with Brunson sometime after the opening of free agency.
