Coach Michael Malone said Jan. 16 that Porter (back) remains without a timeline for making his NBA debut, Nick Kosmider of The Athletic reports. "There are days [Porter is] able to go through parts of practice -- noncontact, of course-- and you see his size, his skill level, his shooting," Malone said. "The guy has a pure jump shot. You forget how long he is. When we do ballhandling and finishing drills, you see his handle and ability to finish, and it's impressive. When we do shooting drills and you see his stroke and how pure it is. It's really encouraging."
