Laviska Shenault Jr. scored all four of No. 21 Colorado’s touchdowns, two on the ground, two through the air, as the Buffaloes remained unbeaten with a win against Arizona State on Saturday.

Shenault Jr. is currently the country’s leading receiver.

Next week Colorado visits USC, seeking its first win over the Trojans in 13 tries.
