Heat churn roster with five Exhibit 10 moves, Nets add Brown

Miami waived Lester Quinones and J'Vonne Hadley, then signed and immediately waived Dennis Smith Jr., according to Anthony Chiang of The Miami Herald. The Heat also signed Gabe Madsen and Kylor Kelley, all on Exhibit 10 deals that could route them to the Sioux Falls Skyforce.

Chiang notes Smith won't get a tryout with Miami despite the agreement. Separately, the Nets officially signed guard Dion Brown to an Exhibit 10 contract after he went undrafted, Brian Lewis of The New York Post reports.
