Approaching the halfway mark of the season, the Colorado football team is still searching for consistency and better play from its offensive line.
Through five games, the Buffaloes (3-2, 0-2 Pac-12) have already used three different starting combinations up front, and it's possible they'll use a new one this week when Arizona (2-2, 0-1) visits Folsom Field.
In last week's 27-23 loss to UCLA, sophomore Isaac Miller finished the game at right tackle, and might have done enough to earn a starting job this week.
"I don't know (if he will start), but he looked good out there when he was doing it," head coach Mike MacIntyre said.
