On a Colorado defense loaded with question marks coming into this season, perhaps the biggest concern about that side of the ball was the Buffaloes' front line.
Last year, nose tackle Josh Tupou and ends Jordan Carrell and Samson Kafovalu were rock solid for the Buffs in the trenches.
That trio played the vast majority of snaps on the line, but all three were seniors, leaving the Buffs to essentially rebuild up front this season.
Two games in, the Buffs are rotating more players up front and finding enough success to keep defensive line coach Jim Jeffcoat pleased with the progress.
