Yahoo Sports senior NBA analyst Kevin O'Connor and contributing writer Tom Haberstroh discuss why last year's first-round pick for the Lakers has the most to prove of any player over the next couple of weeks in Las Vegas.

Walter Clayton Jr. starred in Utah's third win at the Salt Lake Summer League. The national champion at Florida led the Jazz with 20 points to take down Nikola Topic and the Thunder. Kyle Filipowski produced an 18-point, 16-rebound double-double to complement Clayton's scoring outburst. Ajay Mitchell led the Thunder with 19 points.

Former Vol Dalton Knecht competed in the NBA Summer League Sunday. Los Angeles defeated Miami, 103-83, at Chase Center in San Francisco, California. Knecht started and played 22 minutes for the Lakers. He totaled four points, three rebounds, two assists, two steals and one block. Knecht converted 2-of-7 field goal attempts.
