As for the group on the whole, Roberts said that the flaws exposed against Marshall were a combination of things, namely technique and missed assignments.
"It's a combination of both,'' Roberts said. "We were a little bit lazy in some of our technique, which we're going to get fixed. That's my job. Also, some of our assignments, we were too greedy. We didn't have disciplined eyes and that's also my fault.''
"For example, in man-to-man coverage, your eyes should be on the receiver and not on the quarterback or in the backfield,'' Roberts said. "If your eyes are not on [the receiver] then it's going to put you in a position to have a ball caught on you because you're looking [elsewhere] and you react too slowly. Again, that's my job and something I have to take responsibility for.''
Kyeremeh played just 20 snaps, but obviously made an impression as one of those who had fewer missed assignments and technique errors. Certainly that will translate into more opportunities to play on Saturday and all the cornerbacks know that.
"I've had conversations with him and I've had conversations with the older guys and he's going to fit into the mix,'' Roberts said. "It's the older guys' responsibility to keep their jobs and it's Nana's responsibility to take someone's job.
"What we want to foster on this team is good competition. And as long as you're playing well, we're going to reward you with more plays.''
The problem Roberts faces is that if he wants to make changes there aren't a lot of options. Another true freshman, Ricky Rumph, may join the mix, but for now the four who played last week and Rumph seem to be the only ones who have earned a shot. That could change as the season goes along, but for now the group of cornerback candidates will remain pretty much the same.
"Those five corners, that's who we have in the room. We can't make any trades, so those five guys will play in some way,'' Roberts said. "Which two or three or four play, that's up to them. And this week of practice will go a long way toward telling us who thinks they should be in that rotation.''
