Need help optimizing my daily fantasy basketball lineup for tonight's games. I have a tough call between three point guards for my final spot considering recent injury news, back-to-back schedules, and Vegas over/unders. Please run through their matchups, give me a sit/start decision for each option with confidence levels, and list concrete next steps.
