The Dallas Mavericks' undrafted two-way rookie point guard Ryan Nembhard exploded for a career-high 28 points and 10 assists (with no turnovers!) in Dallas' 131-121 win at the Denver Nuggets on Monday.

He is the first undrafted rookie in the modern draft era (since 1967) to record that stat line without committing a turnover.

Ryan is also the first rookie to register at least 25 points and 10 assists in a win since ... his brother Andrew, according to ESPN Insights.

The Mavs NEED this playmaking play to continue as they struggle with depth availability and guard play.
