Fantasy basketball analyst Steve Alexander identifies players whose stock is rising or falling, offering specific add or cut advice. Trey Murphy III of the New Orleans Pelicans has been on a tear, but his value may be at its peak. Alexander suggests trading him now for a top-10 player like Cade Cunningham, citing the Pelicans' poor record and Murphy's injury history as major risks.

Michael Porter Jr. of the Brooklyn Nets is another high-value asset likely to be traded before the February deadline. While he's been a top-20 player, his numbers will drop once he's no longer the primary option. Conversely, Naji Marshall of the Dallas Mavericks is a stable pickup. With multiple Mavericks injured, he's locked into heavy minutes and provides consistent production without the trade risk.

The fantasy landscape shifts weekly, making proactive roster moves essential. Players on losing teams or with injury histories, like Murphy and Porter, present sell-high opportunities. Meanwhile, injury fill-ins like Marshall on contending teams offer reliable value. The key is balancing current production with future outlook as the NBA trade deadline approaches.
