From the AP:
Beck averaged 4.5 points and 1.0 rebounds in two games with the Rockets in the preseason. He averaged 16 points and three assists in the developmental league last season. He played with San Antonio in the summer league before signing a non-guaranteed contract with Houston.
Temple averaged 2.5 points in four games with Houston this preseason. He played four seasons at LSU before signing with Houston as an undrafted free agent.
This comes as no surprise. Temple and Beck, though athletic and talented, were clearly the least NBA-ready players on the roster.
