Most of the NBA Draft focus right now is on the handful of guys at the top of the draft. However, at any given time up to 20 percent of the guys in the league were undrafted (Robert Covington, Jeremy Lin, Seth Curry, Aron Baynes, Wes Mathews, and Kent Bazemore, to name a few). How do those guys get the attention of scouts and GMs and get their chance? Jake Kelfer with the Professional Basketball Combine joins Kurt Helin of NBC Sports to talk about that event — a May event where teams can watch players not at the NBA Combine — and how those players can get a foot in the door. This year, that includes LiAngelo Ball, who will be at the PBC trying to show to scouts exactly what he can do.
