RJ Barrett finalizing extension with New York Knicks, complicating pursuit of Utah Jazz's Donovan Mitchell

New York Knicks guard RJ Barrett is finalizing a four-year rookie extension that could be worth up to $120 million, his agent Bill Duffy of BDA Sports and WME Sports told ESPN on Monday, complicating the franchise's offseason trade pursuit of Utah Jazz All-Star Donovan Mitchell.

Barrett's deal — which makes him the youngest $100 million player in Knicks history at 22 years old — ends several weeks of trade discussions for Mitchell between New York and Utah, and forces the two organizations, if they choose, to start over talks with significantly different considerations because of the «poison pill» provision now in Barrett's deal.

New York president of basketball operations Leon Rose set a Monday night deadline with Utah to reach an agreement on a trade for Mitchell or the Knicks would commit to the Barrett extension, sources said.

While the Jazz-Knicks trade talks intensified and the gap on deal points that included Barrett in the package tightened over the weekend and into Monday, there remained a gulf on reaching a trade for Mitchell, sources said. Once the Knicks and Jazz exhausted discussions Monday night, Rose and Duffy finalized the extension eligible to players out of the 2019 NBA draft class.

Barrett's deal ends a remarkable 23-year drought for the Knicks: He's the franchise's first draft pick to agree to a multiyear contract extension after his rookie deal since Charlie Ward in 1999, according to ESPN Stats & Information research.

Barrett averaged 20 points, 5.8 rebounds and three assists for the Knicks a season ago. He was the No. 3 overall pick in the 2019 draft out of Duke, behind New Orleans' Zion Williamson and Memphis' Ja Morant.

Barrett's one of only five players in NBA history to amass 3,000 points,
