AMES, Iowa — In search of a spark, the Tennessee men’s basketball team looked to its bench, and reserves Lamonte Turner and James Daniel III were more than ready to give the Vols the boost they needed. Turner scored 20 points, Daniel had 16 and 22nd-ranked Tennessee rolled past Iowa State 68-45 on Saturday in the SEC/Big 12 Challenge for its sixth win in seven games. Admiral Schofield had 10 points and seven rebounds for the Vols (15-5), who overcame a horrid start to post their fifth road win of the season. “We played like we try to play in terms of our defense,” said Tennessee coach Rick Barnes, whose team handed Iowa State its worst nonconference loss since rival Iowa beat the Cyclones by 25 in 2001. Tennessee missed 15 of its first 17 shots to fall into a quick early hole.
