The D-League Showcase is underway in Reno and the Springfield Armor will make the first of two appearances Monday on NBA TV at 3:45 p.m. ET vs. the Los Angeles D-Fenders. The D-Fenders feature Gerald Green and two former short-term Nets, Orien Greene, who played under a 10-day contract last season, and Brian Hamilton, who was a training camp invite in both 2008 and 2009. The Armor signed Preston Knowles, formerly of Louisville, Monday.
