As the Buffs come off their bye weekend and begin preparation to host Arizona (0-5, 0-2 Pac-12), head coach Karl Dorrell joined reporters for his Monday press conference.

Dorrell discussed the statuses of a few offensive linemen, talked about what freshman quarterback Brendon Lewis needs to do to continue improving as well as hinted at some "subtle changes" he oversaw over the past week with respect to CU's offense.

Per a report in the Boulder Daily Camera by Mitchell Byars and Pat Rooney, freshman center Carson Lee was charged Wednesday with a pair of assault charges after Lee repeatedly punched a man two Sundays ago.

Lee, who signed with Colorado's Class of 2020, has seen action in two games for the Buffs so far this year.

Dorrell indicated that Lee will remain instated on the team, but will not play, pending the ensuing investigation into the charges against him.

“He is still on our team," Dorrell said. "Obviously, his situation is pending, given how this investigation is going to go. (There’s) really not much other than that to comment about that situation. He’s obviously dealing with legal matters and we’re going to have to let the situation resolve itself in going through the process. There’s really nothing that we’re going to do about it right now."

"He will not be playing or being in the fashion to play right now until this investigation gets more clarity as to where we’re going with a decision. But he’s still on our team. His situation is pending and we’ll kind of just go through the process and go with the facts of the matter that gets resolved, whenever that time frame is.”

Through six weeks of the season, Colorado (1-4, 0-2 Pac-12) has struggled considerably to score points.

The Buffaloes are averaging less than nine points per game against FBS opponents and across college football, at the FBS level, the Buffaloes rank 129th out of 130 programs in total offense, averaging just 239.6 yards per game.

Only Louisiana-Monroe is averaging less, with 239.2 yards per game.

Cries from the CU faithful have grown louder as the Buffs' losing streak has increased to four games, notably for offensive coordinator Darrin Chiaverini to be relieved of his playcalling duties.

Additionally, calls for Lewis to be benched in favor of true freshman Drew Carter have also dominated the Twittersphere, in addition to harsh critiques of Dorrell himself and his offensive staff.

Monday, Dorrell alluded to some minor changes being made, but indicated tht Chiaverini will remain in the playcaller's chair.

“Hopefully the changes we’ve made are going to help us play more efficient and effective football," Dorrell said. "We addressed a lot of things: coaches’ roles, in terms of what the expectations are, the expectations we set for our players and on both sides, the coaching side of it and the players’ side of it, they’ve owned up to we can be better."

"So far so good with that mindset of addressing the issues that are in front of us. And so, we are moving forward, with the subtle changes that we did make.”

Following surgery on his shoulder that sidelined him earlier this spring, sophomore offensive lineman Frank Fillip has been working his way back into the rotation at tackle.

Fillip first saw action this year against Minnesota after missing the first two weeks of the season recovering from injury.

“He is working the rust off and getting in some really good, quality reps with the competitive stuff we have done against each other on the defensive side," Dorrell said. "You can see, even today, it was evident that he’s looking better than what he’s looked in the past. Progress is being made with Frank — Frank’s just catching up with reps and getting himself in football shape and football condition and that mindset of being competitive in these practice sessions."

Graduate transfer tackle Max Wray has also been limited this season, with Dorrell indicating that Wray is steadily returning to practice and could get on track to return to action Saturday against Arizona.

"Max just got out of concussion protocol," he said. "He’s not cleared for full contact yet. I think that will be tomorrow, actually, but he did practice in a limited basis today.”
