Milwaukee Bucks swingman Giannis Antetokounmpo has agreed to a four-year, $100 million contract extension that will be signed Tuesday. In contract talks that played out over the summer, Antetokounmpo expressed a willingness to take slightly less than the max in an effort to help the Bucks retain their young core, sources said. Antetokounmpo averaged 17.2 points, 7.8 rebounds and 4.4 assists last season.
