Bobby Marks takes an in-depth look at New York Knicks guard RJ Barrett 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.

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.
